------- Additional Comments from Gabor Loki <loki at inf.u-szeged.hu>
I have rewritten the whole ARM/Thumb detection according to comment #8 and
comment #17.

The detection of ARM_ARCH_VERSION is almost the same as it was, except
__TARGET_ARM_ARCH macro from RVCT. A new macro - THUMB_ARCH_VERSION - has been
introduced to detect Thumb-2 support. The detection mechanism is similar to the
ARM one. And finally the ARM_THUMB2 platform will be set if the compiler sets
'__thumb2__' macro or '__thumb__' one while THUMB_ARCH_VERSION is 4.
