This ensures that tests actually abort on unimplemented opcodes instead
of just printing them as "Unimplemented Instruction". If used to
disassemble a code region though, we want to ignore unimplemented
opcodes to keep printing remaining valid instructions.
The tests were previously fixed by Deepti in
8fa509d311, but this got partly reverted
on the "Address" refactoring in
2459046c1d.

All we care about w.r.t FieldType is object identity. Moreover,
FieldType does not have its own instance type. Hence it makes no
sense to have the broker know about FieldType at all.

This CL tries to reduce as much as possible the emission of Float64
operations in the inlining of DataView methods.
It adds CheckSmi calls guarding the main variables that the
methods use, and deopts back to the baseline when outside of Smi range.
This should happen extremely rarely anyway, since we don't allow
ArrayBuffers to be larger than that by default.

MIPS64 doesn't support 32-bit compare operations, instead it
relies that values in registers are properly sign extended to
64-bit. Sign extending and then comparing is a costly operation
that we want to avoid. We use costly compare only in those cases
when one operand is signed and other is unsigned.
This CL adds marks PoisonedLoad and ProtectedLoad of unsigned
values as needing full compare instead of optimized one.

Stack parameters on arm64 require padding. Since the stack areas for
parameters and returns should not overlap, we have to pad the parameters
already during the construction of the CallDescriptor so that we can set
the correct stack offset for returns.

The test driver compares command-line arguments against test names
it finds on disk. Using Python's "fnmatch" for this nicely handles
wildcards, but is relatively slow. For given test names that don't
contain any '*', we can use string equality testing, which is much
faster.
Example: the time to evaluate
tools/run-tests.py --arch x64 --mode release \
$(grep 'object-spread' -l -r test/test262/data/test/ | \
sed -E 's|\.js$||' | \
sed -E 's|^test/test262/data/test/|test262/|')
goes from "I gave up and killed the process after several minutes"
to a couple of seconds with this patch.

Liftoff does not use all registers available on x64, so we can use

This generates potentially smaller and more efficient code because we
