Empty function bodies can actually reach the compiler. We could prevent
this by making this a decoder error instead, but that would be a
redundant check, so we should just remove the DCHECK instead.

We want to enable the wasm-bigint implementation by default. However,
at the moment there exist several tests which fail when wasm-bigint
gets enabled. With this CL we adjust or delete these tests so that they
pass once wasm-bigint gets enabled. At the same time we disable these
tests for now, and re-enable them in the CL that flips the flag.

This brings our constants back in line with the changed spec text. We
already use kExprTableGet and kExprTableSet, but for locals and globals
we still use the old wording.
This renaming is mostly mechanical.
PS1 was created using:
ag -l 'kExpr(Get|Set|Tee)Local' src test | \
xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i
PS2 contains manual fixes.

Compilation only stores whether an error has been found, but not the
exact error or it's location. This is generated by running a validation
pass once all wire bytes have been received.
This unifies error messages by removing one more location where we
generate compilation error messages, and makes it deterministic because
a) we always report the error in the first failing function, and
b) if names are present, the error message will always contain the
function name.

This makes the existing error message tests also test the error
produced by asynchronous compilation and instantiation.
It also slightly tweaks the error message to contain the name of the
API function invoked instead of "WebAssembly Instantiation".

This CL revises some of our error messages, and removes unneeded parts
(like "AsyncCompilation: " or "(null): "). It also extends existing
tests to check for the precise error message more thoroughly to detect
changes or nondeterminism earlier.
