For MIPS64, many load/store operations from/to memory emit more then
one instruction. This is the reason for moving them from assembler to
macro-assembler.

This CL fixes the bugs caused by the following CL:
50a394d -- MIPS64: Fix 'MIPS: use DAHI/DATH for li macro on mips64r6.'
Port 1f5b84e467
MIPS: use DAHI/DATH for li macro on mips64r6.
LUI instruction would sign extend into higher 32bits, in that case we might need to use DAHI, DATI to overwrite the extension.
The bug will occur when we are loading some addresses such as 0x00007fffffffxxxx.

Per request in https://codereview.chromium.org/1047213002/
These files will continue to have a lot of churn in next two months
as we finish support for MIPS r6 instruction set. When things settle
down, we will do a clang-format --full to clean them up. For now,
we'd prefer to be able to do easy diffs, and will do incremental
re-formats as we make changes.
