[FT32] Replace hard-coded instruction patterns with macros
The stack unwinder can now use FT32_*() macros to interpet binary instructions instead of local definitions. 2015-09-29 James Bowman <james.bowman@ftdichip.com> * ft32-tdep.c: #include "opcode/ft32.h". Delete local macros IS_PUSH, PUSH_REG, IS_LINK, LINK_SIZE. (ft32_analyze_prologue): Use FT32_* macros.
