Both tables are always updated together and are always accessed
together. Thus merge them, reducing code complexity, but also code
space and overhead for accessing them during runtime. Instead of two
weak global handles, we only need one, which also means one less load
for each indirect call.
Merging them also improves cache locality, since signature and code
address are not stored next to each other in memory, so they will very
likely end up in the same cache line.

We don't currently inline array builtins if we detect any side effects
between the load of the receiver map and the call to the builtin.
The introduction of a map check allows us to be more permissive.

If there is no constructor or species updates on Array or TypedArrays,
then skip lookups of constructor and species so that we can create a new
typed array quickly. This path makes TA.p.slice() 2x faster in fast
cases.

This is the implementation of crrev.com/c/866721 for arm.
Drive-by change: I simplified the slot index calculation.
Original description:
At the moment the slot index is encoded in the opcode. This, however,
sets an upper limit the slot index which is lower than what we want to
have (i.e. < 512). With this change we pass the slot index as an
immediate operand, which does not impose limits on the value it
contains.

This is the implementation of crrev.com/c/766371 for arm64.
Original description:
Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.

On Arm64, the 31 encoding refers to either the zero register or the stack
pointer depending on the instruction. However, in order to distinguish them in
the assembler, the stack pointer has an internal code which isn't 31.
As a result, we need to use the internal code when converting a Register to a
DWARF code.

This will add three gc fuzzing flags with 5% likelihood each to the second
correctness fuzzing config. The random checks are determined by the
top-level random-seed passed to the script.
This change depends on setting the fuzzer random seed as default to the
standard random seed, since the former isn't explicitly passed by
clusterfuzz.
