This is a more canonical type name, and is in line with {kVoidCode}.

Liftoff can currently run out of registers when compiling an atomic
compare-exchange instruction. In order to see this crash, the following
conditions must be met:
- The offset in the instruction doesn't fit in a 12-bit immediate
- Either FLAG_untrusted_code_mitigations is false, or trap handlers are
enabled, so that AddMemoryMasking decides to do nothing
The fix proposed in this CL is just to defer allocation of a temporary
register until after CalculateActualAddress has finished, because it
might have also needed a temporary register.

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.

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.

for loop assignment.

Tests were monolithic, with large loops, and slow on ARM64. Refactor to
small tests so they can be sharded better, reduce page size to 1 to
keep the loops small.
