Add qprocessordetection.h
This detects the target processor based on preprocessor #defines,
setting Q_PROCESSOR_${FAMILY} accordingly. Optional
Q_PROCESSOR_${FAMILY}_${REVISION/VARIANT} #defines are also provided,
usually dependent on how the compiler is invoked.
Currently detected families (and variants) include:
ARM (v5, v6, and v7)
X86 (i386 and x86_64, as X86_32 and X86_64 respectively)
IA-64
MIPS (I, II, III, IV, 32, 64)
Other families that currently are not detected, but Qt has (or had)
support for include:
Alpha
AVR32
Blackfin
PA-RISC
PowerPC (optional 64-bit variant)
S390 (and S390X 64-bit variant)
SH (and SH-4A)
SPARC (SPARC V9)
Detection for these is currently commented out, and can
be easily enabled later.
