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.
