The {SetTraceValue} method was only defined for a set of integer types,
which sometimes lead to ambiguities when using types like {size_t},
{unsigned long} or the like (see https://crrev.com/c/1886912/1).
This CL fixes that by providing a method accepting any integer type.
It also changes the existing methods to avoid the "cast via union"
idiom, and uses memcpy instead.

This moves a series of functions from dictionary.h and hash-table.h

The functions that were moved all somehow use other functions that

A window is a Blink concept. This API marks the context as backing
a detached window. This doesn't necessarily mean that the context is
detached.

Every time a JS function is called within a context that has a non-zero
DetachedWindowReason, Runtime::kReportDetachedWindowAccess is invoked,
which will report this call to Blink via a callback, which in turn can
report number of such calls via UKM metrics.

    [builtins] Move non-JS linkage builtins code objects into RO_SPACE

    Creates an allow-list of builtins that can still go in code_space
    including all TFJ builtins and a small manual list that should be pared
    down in the future.

    For builtins that go in RO_SPACE a Code object is created that contains an
    immediate trap instruction. Generally these Code objects are still no
    smaller than CODE_SPACE Code objects because of the Code object alignment
    requirements. This will hopefully be addressed in a follow-up CL either by
    relaxing them or removing the instruction stream completely.

    In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and
    increases by the same amount.

[builtins] Move non-JS linkage builtins code objects into RO_SPACE

Creates an allow-list of builtins that can still go in code_space
including all TFJ builtins and a small manual list that should be pared
down in the future.

For builtins that go in RO_SPACE a Code object is created that contains an
immediate trap instruction. Generally these Code objects are still no
smaller than CODE_SPACE Code objects because of the Code object alignment
requirements. This will hopefully be addressed in a follow-up CL either by
relaxing them or removing the instruction stream completely.

In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and
increases by the same amount.

Previously only Builtins declared TFJ or CPP in builtins-definitions.h
were converted to direct calls in ReduceJSCall. This allows all
builtins with JS linkage to be converted. To facilitate this, it adds
Builtins::HasJSLinkage(id) that returns true for any builtins with
JSTrampolineDescriptor as their call descriptor.

It also ensures that any JS functions installed by the bootstrapper are
also required to have JS linkage to catch early errors.

These are SSE2 instructions that deal with scalar double precision
values, and look like the packed double precision variant of the
instructions, but with a prefix.

E.g. sqrtpd is 66 0F 51, sqrtss is F2 0F 51.

We don't put this in the same list, even though the implementation
is very similar, because SSE2_INSTRUCTION_LIST is used in other
macros which generate AVX versions of this, and that overlaps with
another macro which generates AVX versions of these X-sd instructions.
I will tease this apart and clean it up in subsequent changes.

- More flexible overloads by disabling generics for overload resolution
  when their constraints are violated.

{AsyncCompileJob::FinishCompile} sometimes takes a long time, especially
if DevTools is open. A lot of time can be spent making the script(s)

visible in the trace.
