This is a source incompatible change for Q_DECLARE_METATYPE(T*),
which now requires T to be fully defined.
The consequences of this are:
* Forward declared types can no longer be declared as a metatype.
(though this is a very uncommon thing to do).
There is a trivial workaround where necessary.

It isn't necessarily that hashing the whole string is the main problem, as the
recently added java string benchmark appears to show, which means the original
purpose of this benchmark is rather voided.
This removal allows gradually repurposing the test towards providing general
benchmarks of QHash performance.

This uses a similar runtime to the approach of sampling part of the string, with
the benefit that it doesn't reduce the sampling to subsections of the string.
Ironically, Java used to only sample parts of the string as well, but found that
it produced too many collisions with certain string types, so they moved to use
this method.

Function pointers used as template parameters must have external linkage
according to the C++ standard. The _mm_lddqu_si128() and
_mm_load_si128() intrinsic functions are declared static in most
implementations, which means we need to wrap them in a non-static
function call to be used.

The benchmark isn't exhaustive, but tests the functions
that are heavily used by QtDeclarative.
For performance reasons, QtDeclarative has its own
implementation of various QChar functions (in
qdeclarativeutils_p.h). But we want to make the actual
QChar functions as fast, so that QtDeclarative can also
use them.
