421fd3929d [wasm] Rename {Get,Set,Tee}Local to Local{Get,Set,Tee}
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.

5bdb13297f [wasm] merge js constants file in module-builder
We noticed that almost every call site were loading both files,
the split isn't necessary anymore.

In some message tests, removed the absolute line number to allow future
changes.

55aed78210 [wasm] Fix constant folding with signalling NaN.
According to the WebAssembly spec no arithmetic operation should ever
return a signalling NaN. With the constant folding in V8, however, it
was possible that some arithmetic operations were elided, and if the
input of the arithmetic operation was a signalling NaN, then also the
result was the same signalling NaN. This CL removes some constant
folding optimizations and adjusts others so that even with constant
folding the result of an arithmetic operation is never a signalling NaN.
