Overhaul the qsimd_p.h: rename macros and update conditionals
The QT_HAVE_xxx macros are replaced with QT_COMPILER_SUPPORTS_xxx.
They indicate that the compiler supports those intrinsics, but not
necessarily that they can be used right now.
ICC and MSVC allow one to use the intrinsics anywhere, but for Qt all
uses of the intrinsics are either in specially-built files, protected
by runtime checks, or they are unconditional (qstring.cpp). So we only
use the intrinsics when the compiler was instructed to generate code
for that instruction set anyway.
