WasmCompileLazy needs to save the content of vector
parameter registers. If Simd is not enabled or the hardware
does not support Simd operations then we need to saves the value of
Double registers instead, therefore we need a way to retrieve the
value of "CpuFeatures::SupportsWasmSimd128()" in builtins
during runtime.

Scopes in V8 are used to guarantee one or more properties during its
lifetimes. If a scope is not named e.g MyClassScope(args) instead of
MyClassScope scope(args) it will get created and automatically destroyed
and therefore, being useless as a scope. This CL would produce a
compiling warning when that happens to ward off this developer error.

Follow-up to ccrev.com/2552415 in which it was introduced and
implemented for Guard classes.

This CL makes the metadata offsets stored in Code headers
relative to the start of the metadata section (instead of to
the start of the instructions section).

In a follow-up, metadata for embedded builtins will be moved
from the .text section (with r-x or --x permissions) to the
.rodata section (with r-- permissions).

Drive-by: Simplify invariants around section alignment. A
new invariant is that the end of the instruction section is
aligned to Code::kMetadataAlignment.
Drive-by: Ensure trampoline Code objects contain no metadata
(metadata offsets all refer to the off-heap metadata section).

On mips platform, call operations may be followed by trampolines, which
leading to wrong information of the call instr's location in safepoint.
This CL fix it by adding a last_call_pc_ to record the location.

Besides, this CL also fix a bind operation in CheckTrampolinePool, which
may try to use trampoline before it's emission.
