1. Extends lexer so digit or string can be followed by underscore '_' and
alphanumeric defining literal.
2. Extends parser so it accepts operator"" _abc(...) user-defined literal
definition.
3. Adds Token::Flags.userDefinedLiteral bool flag field representing if token
carries user-defined literal.
4. Adds C++11 auto tests case with: 12_km, 0.5_Pa, 'c'_X, "abd"_L, u"xyz"_M
5. All optional suffix scanning methods now return boolean if the suffix was
found.
6. Adds C++ Lexer tests for user-defined literals with C++11 feature enabled.
This change however does not make QtCreator understand user-defined literal
semantics, e.g. properly resolve type when applying custom literal operator.

...in order to stop memory intensive parsing for invalid code.
Parsing the test data/snippet "hard" led to a memory consumption of
about 5.5MB and this could easily get up to hundreds/gigabytes by adding
some more "if_<bool_<true>,\n" lines. With the caching, we are at about
1.0MB, even if more lines are added.
The "memory consumption" was measured with valgrind-massif. The stated
numbers are the reported peaks.

In the struct _Wrap_alloc (see test code) the rebind struct has
_Wrap_alloc as parent. However, within rebind the typedef of type
_Wrap_alloc has rebind as parent.
We will refactor that in master by introducing a "parent iterator"
class checking for cycles, so the client code looks less noisy.

For the semantic info document we do not expand function like macros and
because of that certain macro invocations lead to invalid code that we
need to handle, e.g.:
Q_GLOBAL_STATIC(CppTools::SymbolFinder, symbolFinder)
class Foo {};
This change makes parsing Foo in the semantic info document successfully
again, which affects highlighting of that class.

This mainly takes CppEditorSupport apart.
* Parsing is now invoked by CPPEditorDocument itself by listening to
QTextDocument::contentsChanged().
* Upon construction and destruction CPPEditorDocument creates and
deletes an EditorDocumentHandle for (un)registration in the model
manager. This handle provides everything to generate the working copy
and to access the editor document processor.
* A CPPEditorDocument owns a BaseEditorDocumentProcessor instance that
controls parsing, semantic info recalculation and the semantic
highlighting for the document. This is more or less what is left from
CppEditorSupport and can be considered as the backend of a
CPPEditorDocument. CPPEditorDocument itself is quite small.
* BuiltinEditorDocumentProcessor and ClangEditorDocumentProcessor
derive from BaseEditorDocumentProcessor and implement the gaps.
* Since the semantic info calculation was bound to the widget, it
also calculated the local uses, which depend on the cursor
position. This calculation got moved into the extracted class
UseSeletionsUpdater in the cppeditor plugin, which is run once the
cursor position changes or the semantic info document is updated.
* Some more logic got extracted:
- SemanticInfoUpdater (logic was in CppEditorSupport)
- SemanticHighlighter (logic was in CppEditorSupport)
* The *Parser and *Processor classes can be easily accessed by the
static function get().
* CppHighlightingSupport is gone since it turned out to be useless.
* The editor dependency in CompletionAssistProviders is gone since we
actually only need the file path now.

For expression statements like "(g(g(g(...(g(0))...))))" we reparsed
quite much again and again for nothing. The high-level trace for this
expression looks like this:
parseCastExpression
parseTypeId
parseAbstractDeclarator
parseAbstractCoreDeclarator
parseParameterDeclarationClause (--> DEEP)
...
parseUnaryExpression
...
parseCorePostfixExpression
parseTypeId (--> DEEP)
parsePrimaryExpression (--> DEEP)
Especially parseTypeId is expensive in this case and it's called two
times, both from the same token (index).
With this patch, we remember for certain ASTs the parse results and
re-use them when needed.

A case or a default statement must be followed by another statement.
When a such a case (or default) statement is followed immediately by
another case (or default) statement, then this would create a linked
list, and the parser will recurse to parse such input.
In order to prevent the parser running out of stack space while
recursing, parse this corner case by blocking parsing a labeled
statement as the first statement after a labeled statement.
The advantage is that these statements do not form a linked list, so any
subsequent visitation of the AST won't run out of stack space either.
