Accept any type in the intrinsics definition, and then manually
validate that there are no atomics in the type. Add manual E2E tests
for composite types.
Use the BuiltinPolyfill transform to implement it for all backends.
Update the uniformity analysis with special-case tags for the builtin.

Fixes a problem where the regex fuzzer would identify '==' as a
candidate operator for replacement, but where the replacement code did
not actually handle the '==' case.

Fixes the regex fuzzer so that when searching for an operator to
replace, it takes account of the fact that the string being searched may
be very small, avoiding an issue where unsigned integer underflow would
occur.

This is part of a workaround in the Chromium build infrastructure for
the fact that on Mac, the linker tends to strip LLVMFuzzer*
implementation because of how they are loaded/used.
All of the rest of the machinary is already setup and working, just
need to actually include the header. Dawn and other fuzzers use this
same fix.

Adds random swizzle operations to candidate vector expressions.
Also excludes certain common keywords from the set of identifiers that
are matched by the regex fuzzer, which will serve to make other
mutations performed by the regex fuzzer more preise.

The kokoro bots are running at a different level of verbosity than
the presubmit check. This CL ups the verbosity level for presubmit
to match kokoro and suppresses any new lint warnings which are

The set of always removed filter options used by PRESUBMIT are
copied into the CPPLINT.cfg main file in order for kokoro to
