The stack check instruction sequence is pattern-matched in
instruction-selector-{ia32,x64}.cc and replaced with its own specialized
opcode, for which we later generate an efficient stack check in a single
instruction.
But this pattern matching has never worked for CSA-generated code. The
matcher expected LoadStackPointer in the right operand and the external
reference load in the left operand. CSA generated exactly vice-versa.
This CL does a few things; it
1. reverts the recent change to load the
limit from smi roots:
Revert "[csa] Load the stack limit from smi roots"
This reverts commit 507c29c940.
2. tweaks the CSA instruction sequence to output what the matcher
expects.
3. refactors stack check matching into a new StackCheckMatcher class.
4. typifies CSA::PerformStackCheck as a drive-by.

On 64 bit architectures, reading memory in wasm requires a conversion
of the 32 bit index into a 64 bit value. For this, we generate a
ChangeUint32ToUint64 graph node, which later materializes as a move
and hence consumes a register. This generates unneccesary register
pressure, especially with gvn enabled.
Now, the WasmGraphBuilder will emit a IntPtrConstant node right
away if the index is a constant.

Previously, we sent a critical low memory pressure notification when
attempting to commit WASM code when the code manager was near the
limit for total amount of code allocated.
https://chromium-review.googlesource.com/c/v8/v8/+/1073412 "fixed" that,
but it causes OOMs on Windows.
Since we no longer have the isolate on the code manager, and thus cannot
send this notification on commit, send the notification upon the next
module creation.
This is still not optimal, but should fix OOM issues for lots of
small modules on Windows.
