b497a34655 CppEditor: Fix always-false-condition
The condition didn't make sense. tk.kind() can't be < T_FIRST_QT_KEYWORD
*and* tk.kind() > T_LAST_KEYWORD at the same time.

c56b999fff C: Parser: Support parsing of c99 designated initializers
In case:

    int a[6] = { [4] = 29, [2] = 15 };
    struct point { int x, y; };
    struct point p = { .y = 3, .x = 2 };

Grammar change when c99 language feature is enabled:
old grammar:

    braced-init-list :: '{' initializer-list '}'

new grammar:

    braced-init-list :: '{' designated-initializer-list '}'
    designated-initializer-list :: designated-initializer (',' designated-initializer )*
    designated-initializer :: designator* initializer-clause
    designator :: '.' identifier
                | '[' constant-expression ']'

70122b3061 C++: Support for UTF-8 in the lexer
This will save us toLatin1() conversations in CppTools (which already
holds UTF-8 encoded QByteArrays) and thus loss of information (see
QTCREATORBUG-7356). It also gives us support for non-latin1 identifiers.

API-wise the following functions are added to Token. In follow-up
patches these will become handy in combination with QStrings.
    utf16chars() - aequivalent of bytes()
    utf16charsBegin() - aequivalent of bytesBegin()
    utf16charsEnd() - aequivalent of bytesEnd()

Next steps:
 * Adapt functions from TranslationUnit. They should work with utf16
   chars in order to calculate lines and columns correctly also for
   UTF-8 multi-byte code points.
 * Adapt the higher level clients:
    * Cpp{Tools,Editor} should expect UTF-8 encoded Literals.
    * Cpp{Tools,Editor}: When dealing with identifiers on the
      QString/QTextDocument layer, code points
      represendet by two QChars need to be respected, too.
 * Ensure Macro::offsets() and Document::MacroUse::{begin,end}() report
   offsets usable in CppEditor/CppTools.

Addresses QTCREATORBUG-7356.

e148d030f5 C++: Introduce C++11 raw string literals
Although they are now supported by the lexer
and parser, it is worth to remind that we still
need to address an issue concerning the highlight
of multiline literals (which with the advent of
the new raw strings will become more common).

621e5c3dbe C++: Parse emit/Q_EMIT properly
The parser now understands emit/Q_EMIT as an expression statement.

Also, the recent fixes in the preprocessor introduced a side-effect
in the hanlding of code such as: emit signal(); Member signal started
being treated as a local use (parsed as a declaration) and possibily
being highlighted as unused variable.

Previously that worked by accident since there was an inconsistency
in the preprocessor on which only object-like macros were being
expanded even when the "no expand" flag was set. Then, the code
mentioned above was being parsed as an expression, what kind of worked.

d6ccffc06c C++: Core changes in preprocessing
Summary of most relevant items:

- Preprocessor output format change. No more gen true/false. Instead
  a more intuitive and natural expansion (like from a real compiler) is
  performed directly corresponding to the macro invocation. Notice that
  information about the generated tokens is not lost, because it's now
  embedded in the expansion section header (in terms of lines and columns
  as explained in the code). In addition the location on where the macro
  expansion happens is also documented for future use.

- Fix line control directives and associated token line numbers.
  This was not detected in tests cases because some of them were
  actually wrong: Within expansions the line information was being
  considered as originally computed in the macro definition, while
  the desired and expected for Creator's reporting mechanism (just
  like regular compilers) is the line from the expanded version
  of the tokens.

- Do not allow for eager expansion. This was previously being done
  inside define directives. However, it's not allowed and might
  lead to incorrect results, since the argument substitution should
  only happen upon the macro invocation (and following nested ones).
  At least GCC and clang are consistent with that. See test case
  tst_Preprocessor:dont_eagerly_expand for a detailed explanation.

- Revive the 'expanded' token flag. This is used to mark every token
  that originates from a macro expansion. Notice, however, that
  expanded tokens are not necessarily generated tokens (although
  every generated token is a expanded token). Expanded tokens that
  are not generated are those which are still considered by our
  code model features, since they are visible on the editor. The
  translation unit is smart enough to calculate line/column position
  for such tokens based on the information from the expansion section
  header.

- How expansions are tracked has also changed. Now, we simply add
  two surrounding marker tokens to each "top-level" expansion
  sequence. There is an enumeration that control expansion states.
  Also, no "previous" token is kept around.

- Preprocessor client methods suffered a change in signature so
  they now receive the line number of the action in question as
  a paramater. Previously such line could be retrieved by the client
  implementation by accessing the environment line. However, this
  is not reliable because we try to avoid synchronization of the
  output/environment lines in order to avoid unnecessary output,
  while expanding macros or handling preprocessor directives.

- Although macros are not expanded during define directives (as
  mentioned above) the preprocessor client is now "notified"
  when it sees a macro. This is to allow usage tracking.

- Other small stuff.

This is all in one patch because the fixes are a consequence
of the change in preprocessing control.

23c637c4f6 C++: Introduce unicode char/strings support
Those are the types char16_t and char32_t along with the new
char/string literals u'', U'', u"", u8"", and U"".

This is particularly important for the use of QStringLiteral
since in some platforms it relies on expansion such as above.

Note: The string literals quickfixes still need some tunning.
