[PATCH 11/20] MIPS/GAS: Remove dead base register code

[Maciej W. Rozycki]

Hi,

 This change removes dead code to handle "(4)", "(5)" and "(-)" base 
register format specifiers.  They are nowhere used in opcode tables nor in 
macro_build() invocations and "4" and "5" have been since taken for use as 
some DSP ASE immediate specifiers.

	gas/
	* config/tc-mips.c (mips_ip)['(']: Don't let '4', '5' or '-'
	as a base register specifier.

 OK to apply?

  Maciej
