Define DBX_REGISTER_NUMBER for IA MCU

Since IA MCU uses the same debug register map as Linux/x86, we copy DBX_REGISTER_NUMBER together with TARGET_ASM_FILE_START_FILE_DIRECTIVE and ASM_COMMENT_START from i386/gnu-user.h to i386/iamcu.h.

* config/i386/iamcu.h (TARGET_ASM_FILE_START_FILE_DIRECTIVE): New. Copied from config/i386/gnu-user.h. (ASM_COMMENT_START): Likewise. (DBX_REGISTER_NUMBER): Likewise. --- gcc/config/i386/iamcu.h | 11 +++++++++++ 1 file changed, 11 insertions(+)
