Add architecture specific target option macros

Browse Source 
These macros are defined in target.hpp. This commit adds the macros:

NOINLINE - Never inline the function
ALWAYS_INLINE - Force the function to be inlined (also adds the inline
attribute to the function)

TARGET_ARM_MODE - Compile all future functions in ARM mode until
TARGET_END_MODE is reached. No-op if not compiling for ARM.
TARGET_THUMB_MODE - Compile all future functions in thumb mode until
TARGET_END_MODE is reached. No-op if not compiling for ARM.
TARGET_END_MODE - Undo the last TARGET_*_MODE option.

ARM_MODE - Compile this function in ARM mode.
THUMB_MODE - Compile this function in thumb mode.
