This is a small refactoring that moves the WasmCodeManager and
CompilationManager from being a part of the Isolate directly to living in a new
WasmEngine object. This makes it easier to change Wasm components without
rebuilding so much of V8, and also enables future changes to Wasm without
affecting unrelated parts of V8.

This is to avoid calling AssembleTailCallBeforeGap and AssembleTailCallAfterGap
directly where possible (so making the tests less dependent on the code generator
interface when we're not directly testing it). It also makes sure that the
instruction we pass to AssembleTailCallBeforeGap and AssembleTailCallAfterGap is
indeed a tail call, with the immediate argument that specifies the stack delta.
This is to prepare for padding arguments for arm64 JSSP removal. We will need to
store padding in AssembleTailCallAfterGap, which will need the information from
a TailCall instruction.

This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.
Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.
Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

This is the first step towards wasm code sharing. This CL moves wasm
code generation outside the JavaScript GC heap using the previously -
introduced WasmCodeManager (all this, behind the --wasm-jit-to-native
flag).
See design document: go/wasm-on-native-heap-stage-1
This CL doesn't change other wasm architectural invariants. We still
have per-Isolate wasm code generation, and per-wasm module instance
code specialization.

This is reland of 3e0bf580e8
Original change's description:
> This commit is a step toward enabling test-run-wasm-simd tests for MIPS.
> 36 of those were failing in V8 builtin simulator because some instructions
> were not implemented. Also there are minor fixes to some of the already
> implemented instructions.

> This commit has only 32-bit implementation. After review I will add

In a recent CL I introduced module-level CodeSpaceMemoryModificationScopes,
which means that the number of CodeSpaceMemoryModificationScopes which
are opened aside from TurboFan compilation is not linear in the number
of functions anymore. In that CL, however, I did not remove scopes which
became obsolete. This CL removes now these obsolete scopes, and
introduces some scopes where shared code was used from outside the
compilation logic.

Change the existing uses of the harmony-class-fields flag to
harmony-public-fields so that we can stage this separately
from the upcoming harmony-private-fields to get some
clusterfuzz coverage.

This enforces that we use ParseExpressionCoverGrammar, and not ParseExpression,
for several tricky cases. Also clarify comment on ParserBase::ParseExpression().

Besides avoiding the weird hack of inserting a statement at the 0th
index of the function body, we also avoid allocating (and initializing)
the variable if it's unreferenced (which I'd wager is the common case).
