This CL fixes all occurences that don't require special OWNER reviews,
or can be reviewed by Michi.
After this one, we should be able to reenable the readability/check
cpplint check.

New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

Instead of allocating and embedding certain heap numbers into the code
during code assembly, emit dummies but record the allocation requests.
Later then, in Assembler::GetCode, allocate the heap numbers and patch
the code by replacing the dummies with the actual objects. The
RelocInfos for the embedded objects are already recorded correctly when
emitting the dummies.

For int16 imm values Subu would emit addiu with -imm value, but doing
this with min_int16 would overflow and produce incorrect result. This is
fixed by checking if -imm is int16. A test for this case is created.
An optimization is also added for values imm where we cannot just emit
addiu and loading -imm to a register takes one instruction using ori.
Then instead of loading imm with lui;ori and subtracting with subu, we
can load -imm with ori and add with addu.

For MIPS32, instructions ldc1 and sdc1 are moved into macro-assembler
and renamed as Ldc1 and Sdc1. The reason for placing them into
macro-assembler is that they emmit two or three instructions.

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.
