Both macros currently call a function with individual CHECKs, which
makes error messages only show that one part of the equality check (and
not the the actual float values), and hides the actual location of the
check.
This CL refactors this such that the actual value is shown (just as
with other CHECK_EQ macros) and it shows the right file name and line
number.

When collecting the values of an object with Smi or Object elements
kind, there are no allocations, so we don't need to create a short-
lived handle for each value. This gives a small performance benefit
in general, and in particular on ia32 by reducing register pressure
causes clang to spill less, which fixes the regression in the issue
mentioned below.

Not all 2 or 3 letter language codes are canonical. Some of them need
to be canonicalized.
Specifically, exclude {jw,ji,iw,in} and all three-letter codes from the
fast path except for 'fil'.
{jw,ji,iw,in} are deprecated ISO 639 codes for
{Javanese, Yiddish, Hebrew, Indonesian}. They should be
canonicalized to {jv,yi,he,id}. So, do not return early
in the fast path, but pass it down to the full canonicalization.
In addition, there are 70+ deprecated 3-letter codes that need to be
replaced by their modern equivalents. Instead of checking and replacing
in v8, just pass them to ICU to handle.
Along with the following ICU change, two more tests will pass.
https://chromium-review.googlesource.com/c/chromium/deps/icu/+/1026797
These two tests still fail because of the disagreement between ICU and the test
expectations about 5 grandfathered tags with no preferred value (e.g.
i-default, zh-min, cel-gaulish).
