[PATCH] [mips] Add assembler support for the .cprestore directive.

[Toma Tabacu]

Hi dsanders,

This assembler directive is used in O32 PIC to restore the current function's $gp after executing JAL's. The $gp is first stored on the stack at a user-specified offset.

It has the following format: ".cprestore 8" (where 8 is the offset).

This also fixes http://llvm.org/bugs/show_bug.cgi?id=20967.
