Assembler::PopAndReturn expects an Integral type so convert argc from a
SMI if necessary.
On 64-bit architectures, convert 64-bit immediate pop values into
32-bit values. This is safe since the conversion checks that nothing
was truncated.
Also change CodeStubArguments unit tests to use PopAndReturn rather
than Return.

The method {SpillAllRegisters} should really just spill registers, and
not also constants. Also, since more code is inlined into that method
now, we can optimize it to update register use counters only once in
the end, since no used register should be left after executing this
method.

This is the implementation of crrev.com/c/866721 for ia32.
Drive-by change: Clean up the slot index calculation.
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 adds a new simplified operator NumberToString, which just lowers to
a call to the NumberToString builtin, and hooks that up to the typed
lowering (addressing a long-standing TODO).
Drive-by-fix: Also remove the %NumberToString runtime entry, and just
always use the %NumberToStringSkipCache entry from CSA, since we only
go there if the cache lookup already failed.

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.
