 I have committed this change now.

2014-12-12  Maciej W. Rozycki  <macro@codesourcery.com>

	gdb/
	* mips-tdep.h (MSYMBOL_TARGET_FLAG_MIPS16): New macro.
	(MSYMBOL_TARGET_FLAG_MICROMIPS): Likewise.
	* mips-tdep.c (mips_elf_make_msymbol_special): Use the new 
	macros.
	(msymbol_is_mips, msymbol_is_mips16, msymbol_is_micromips):
	Likewise.
