MIPS: add .module mipsREV to all output asm file
Currently, the asm output file for MIPS has no rev info.
It can make some trouble, for example:
assembler is mips1 by default,
gcc is fpxx by default.
To assemble the output of gcc -S, we have to pass -mips2
to assembler.
gcc/ChangeLog:
* config/mips/mips.c (mips_module_isa_name): New.
mips_file_start: add .module mipsREV to all asm output
