WASM interpreter requires that parameters are stored in big-endian natural
memory order (higher bits on lower addresses and lower bits on higher address).
On the other hand, WASM compiled code naturally stores data in memory in
little-endian order. This CL implements big-endian support for passing
double and int64 parameters to WASM interpreter.

This hack is causing false "last-resort" garbage collections.

When incremental marking is in progress and overshoots the limit,
our heuristics in the allocator request finishing the mark-compact
because V8 is in optimize-for-memory mode.

However, the mark-compact gets replaced by scavenger which leads to
retrying the allocation two times and eventually doing last resort GC
(which throws away all the marking info).

BinopMatcher does not notify the reducers using it when it flips inputs to commutative operators. This leads to value numbering not being re-executed in this case. Together with the fact that value numbering might still reduce such a modified node in the case of a hash collision merging the buckets of two equivalent nodes, this leads to unpredictable behaviour.

This is the easiest fix for the problem: Always running value numbering last. This is also a performance improvement because value numbering never changes but only replaces nodes.

Turbofan is a lot slower than Crankshaft at constructing TypedArrays,
because we always go to the C++ builtin. Port the builtin to CSA
to improve performance, and to clean up the implementation, which is
split across multiple files and pieces at the moment.

This CL increases the performance with --future to roughly the same
as with crankshaft.
