[MIPS] Fixing FP registers fs0 and fs1 corruption bug.

There was an earlier patch which fixed the same problem in the
"mterp" code. This patch is for fixing the JIT template code.

For performance reasons, we don't want to use "callee saved" FP registers.
The fix is to just use temporary FP registers instead.
