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 507c29c9. 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.
