Fix 29bb707e9b
Compilation on GYP fails due to missing OnCriticalMemoryPressure
overload that accepts size_t parameter. In this case the compiler
complains about hiding virtual function.
This patch reintroduces the missing functions.

Web platform tests that allocate 600 memories fail due to this. (This seems to also interfere with tests on the same shard).

- Adds overload to v8::Platform that will make it easier for embedders to
maintain a reserve of address space for large, contiguous allocations.
- Rewrites retry logic using loops.
- Moves retry logic from some VirtualMemory allocation functions to AllocPages.

We collect instance type statistics in FatalProcessOutOfMemory into an
array, which is allocated to the max instance type value. While we want
to leave space to ensure new instance types do not affect constants in
the API, we can be more frugal.
We currently serialize 350 maps into the startup/context snapshot. Even
if we assign a distinct instance type to each of these maps, we would
still have more than enough to spare with this change.

- Instantiation errors are no longer recorded. If instantiation fails,
the module(s) are reset to "uninstantiated". When instantiation is
re-attempted, the thrown exception will be fresh.
- Instantiation can succeed even where there are modules in the graph
that previously failed evaluation.

This is the implementation of crrev.com/c/766371 for mips64.
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 32-bit platforms, float64 stack returns take 2 stack slots. In the
implemention of the kArmPeek instruction we assume that provided slot
index points to the first stack slot. However, due to an off-by-1 issue
the provided slot index pointed to the second stack slot. This CL fixes
the problem and generalizes an existing test which reproduces it.

For numbers, `JSGraph::Constant(Handle<Object> value)` first checks the
type of `value`, and then calls `JSGraph::Constant` for its type, which
in turn performs some further checks before returning a value.
This patch saves a few `if` checks by making the following changes:
- JSGraph::Constant(0) → JSGraph::ZeroConstant()
- JSGraph::Constant(1) → JSGraph::OneConstant()
