Recently tons of warnings show up for presumably "problematic"
singned <-> unsigned and size conversions.
The Qt side uses 'int', and that's the biggest 'integration surface'
for us, so instead of establishing some internal boundary between
signed and unsigned areas, push that boundary out of creator core code,
and use 'int' everywhere.
Because it reduces friction further, also do it in libcplusplus.

In some (legacy) C files, new and delete may be used for regular identifier.
There are some limitations:
* Header files have no 'implicit' type, and may be parsed as C++ or ObjC depending on the
other files in the project.
* QMakeProject use a single ProjectPart for C and C++ files, so there will still be the issue.

...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

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.

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.

Until now std::vector::at() was used to access the elements. This is
handy for debugging since an exception is thrown for invalid indices,
but it does not stop Qt Creator from crashing because exceptions are not
caught.
This is especially a problem for the parser, which has to look ahead via
LA(n), which accesses TranslationUnit::_tokens.
With this patch, explicit bounds checking is done before accessing the
elements and thus calls to
std::vector::at() // bounds checking, throwing out_of_range
were replaced by calls to
std::vector::operator[]() // no bounds checking, not throwing out_of_range
Measuring the parse time for the Qt Creator project shows that there is
no slowdown. In both cases, with and without the patch, about 15s are
needed on the authors machine.

class Arg;
class Other;
class Foo {
