This improves conformance with ACLE 6.4.1. Define additional macros that
indicate support for the ARM and Thumb instruction set architecture. This
includes the following set of macros:
__ARM_ARCH
__ARM_ARCH_ISA_ARM
__ARM_ARCH_ISA_THUMB
__ARM_32BIT_STATE
These help identify the environment that the code is intended to execute on.
Adjust the handling for ACLE 6.4.2 to be more correct. We would define the
profile as a free-standing token rather than a quoted single character.
