While marking uses, record what values are used inside a loop, but
defined outside of it. Then, on the loop end, extend the lifetime of
these values.

Memory64 currently does not use trap handling, so we should not allocate
a guard region (10GB total reservation).
This is implemented by adding a {WasmMemoryFlag} enum in the backing
store header, which replaces the previous {MemoryIndexType}. The flag is
not stored with the backing store, as the backing store does not care
about the index type, and we might want to share the same backing store
for memory32 and memory64 (if sizes permit this).
Instead, we (still) store the flag with the WasmMemoryObject and pass it
to the backing store methods.

Register merges participate in the same parallel gap move as phi inputs,
but their allocation is not aware of the phis' existence (since the
register merge allocation sees the register state _before_ phi input
allocation, which is because that's what parallel move requires). This
means that they might move into a register that is used by a Phi, and
possibly will clobber its value.

Avoid this by recording what registers phis move values into during code
gen, and skipping register moves into those registers. Also DCHECK that
the recorded gap moves can't clobber a target register from a previous
gap move. Additionally, add printing for register merges (both in
regalloc tracing and graph printing).

whether an address that may be an inner pointer is contained in some
allocated (normal or large) page. To achieve this, the CL introduces a
