Jiaxun Yang 7c66501861 [libcpu] Refine MIPS common code 
MIPS common code was highly duplicated, This commit
is a attempt to clean-up and refine these code.

The context and exception handle flow is mostly identical
with Linux, but a notable difference is that when FPU enabled,
we save FP registers in stackframe unconditionally.
