Preprocessor: improve ACLE 6.4.1, 6.4.2 support 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. llvm-svn: 210991
