[patch ping] GAS supports for MIPS32 DSP ASE

[Chao-ying Fu]

Hello, All,

  We would like to contribute GAS supports for MIPS32 DSP ASE.
The patch was posted in June and stayed there then.
So, I posted the whole patch again.  GAS "make check" is ok under
mipsisa32-elf and mipsisa64-elf with mips-sim.

  Could any binutils maintainers review the code?  Thanks a lot!

Regards,
Chao-ying
