The previous approach to this (in 1b1de2d2) did not work well with
bots that intentionally run no tests. But I think this warning message
is still useful for developers.

Revert of Debugger: clear shared function info list when recompiling for liveedit. (patchset #1 id:1 of https://codereview.chromium.org/1270313003/ )

Reason for revert:
Sorry for revert, but this change breaks one of the webkit-unit-tests.

Example here: https://storage.googleapis.com/chromium-layout-test-archives/V8-Blink_Win/1178/layout-test-results/inspector/sources/debugger/live-edit-no-reveal-diff.txt

Not sure if the old expectations were right, or the new ones are. :)

First step to simplify the TypeofStub. This is similar to the

There's no need to have one InstanceType per SIMD primitive type (this
will not scale long-term).  Also reduce the amount of code duplication
and make it more robust wrt adding new SIMD types.

This avoids many back-and-forth calls to the runtime.

This also slightly changes the way we avoid getters. Previously, we circumvent getting the name property of ReferenceError, SyntaxError and TypeError due to crbug/69187 (in order to avoid leaking information from those errors through a 'name' getter installed on their prototypes). Now we do that for all errors created by V8.

This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.

Also the number of includes inside the v8.h file has been drastically
reduced. Basically the last missing piece is the inclusion of the big
objects-inl.h file.

This in turn makes many headers follow the IWYU principle.

This is a first step towards constraining down the heap interface to
just the heap.h file. Note that many includes still leak through that
file to the global "src" directory, but there now is a single place
controlling which declarations leak that way. Especially inclusion of
inline header files within "heap" has been limited drastically.

When a (prototype) map registers as a user of its own prototype, it now remembers the index in that prototype's registry where it is listed.
This remembered index is used on un-registration to find the right slot to clear without walking the entire registry.
Compaction of the registry must update all entries' remembered indices.
