the problem is that we call irregexp code in two ways:

1. CallCFunction9 from CSA builtins
2. Through GeneratedCode::Call from the runtime.

1 is a standard C call and expects the target to be a FD,
2 is our own implementation where we dynamically generate a FD.
So there's a mismatch between the two.

We have to create WasmExportedFunction objects for any WebAssembly
function which may escape a WebAssembly instance. Up until now we
created these WasmExportedFunction objects eagerly during instantiation
time: for any exported function, and any element in an exported table we
create such an object.

With the anyref proposal, the table.get instruction can allow any
function in a table to escape its instance. Therefore we would have to
create a WasmExportedFunction object for any function which is put into
a table.

With this CL we create WasmExportedFunctions for table entries lazily.
We initialize tables with placeholders consisting of the instance and
the function index. If we encounter a placeholder in table.get, we
create the WasmExportedFunction for the expected function to return it.

RotateRight32 needs a "number of bits" operand in the range 0..31.
Thankfully that's how x86 shift instructions behave anyway, and
how the bitwise shift operators in JavaScript are spec'ed, so this
fix is unobservable in non-UBSan builds.

RemoveArrayHolesGeneric can be used for length values anywhere in
the uint32_t range, so it must not implicitly cast those to int.
That actually caused an observable bug where a proxy's traps would
not get called at all, but only for huge "length" properties, where
the entire operation would also be painfully slow.

This change enables clean-up of weak map entries in the
scavenger of the weak map is in the young generation.
With this change, the scavenger treats keys in ephemerons as
weak instead of strong, but does not implement full ephemeron
semantics: Values are treated always as strong, independently
of whether the key is live or not.

This approach ensures that no value is cleaned up accidentally.
After scavenging, all entries with dead keys are removed from
weak maps. After that, some values that are not referenced anywhere
anymore might still be in the heap, and those can be cleaned up
in the next scavenge.

What the scavenger does, amounts to one iteration of the
fixed-point algorithm required to implement ephemeron semantics.
We hope that this is a reasonable trade-off between time spent
tracing and cleaned-up entries.

This change does not affect weak maps that reside in old space.

After introducing the new pointer-containing Object class in V8 (see
https://docs.google.com/document/d/1_w49sakC1XM1OptjTurBDqO86NE16FH8LwbeUAtrbCo/edit),
gcmole stopped finding errorneous usage of raw pointers in functions that could
trigger GC. This CL modifies the heuristics of the tool to classify Object and
MaybeObject instances as raw pointers, thus giving back the missing warnings.

Updated the gcmole implementation to support modern llvm (tested with llvm 8.0)
for which additional support for MaterializeTemporaryExpr, ExprWithCleanups and
UnaryExprOrTypeTraitExpr was needed.

Basic tests are added to make it harder to introduce such errors without
noticing in the future.

This version gives a lot of false positives when ran on the whole project, see
https://docs.google.com/document/d/1K7eJ0f6m9QX6FZIjZnt_GFtUsjEOC_LpiAwZbcAA3f8/edit

Some windows toolchains contain a macro name 'FormatMessage', making
compilation fail, see e.g.
https://ci.chromium.org/p/v8/builders/try/v8_win64_msvc_compile_rel/b8919741418899023808.

Hence rename {MessageFormatter::FormatMessage} to
{MessageFormatter::Format}.

Emitting bytes to the Uint8Array directly speeds up generation of
binaries enormously.
On the limits-any.js spec test (which creates huge modules), the
execution time of an optdebug build reduces from 286 seconds to 61
seconds.
