This CL replaces some Handles which can be empty by MaybeHandle. This documents that they can be empty, and forces a check before using them. R=ahaas@chromium.org Change-Id: Iefb9ae76617c45d2304b0a620dc082ab9c7b0585 Reviewed-on: https://chromium-review.googlesource.com/574593Reviewed-by:

Moves the creation of shared function infos and the scripts shared function info array (for top-level code) to be in the FinalizeUnoptimizedCompilation step when not compiling with Full-codegen. This is needed in order to avoid accessing the heap between parse and compile.

en_US_POSIX is ICU's fallback locale on POSIX platforms for when it cannot detect a default locale. Consider it equivalent to en-US.

This refactoring makes some parameters const, and does not rely on the fact that inputs are passed via NodeVector. Both changes are needed for an upcoming refactoring of the wasm decoder.

Signature maps should only be updated, but never copied. We had a bug because we accidentally updated a copy of the map. This refactoring prevents any such bugs in the future, and fixes more occurences where we accidentally copied structs containing a signature map (the move-only constraint also extends to all structs containing a signature map). Drive-by: Make InstanceBuilder::NeedsWrappers const.

We optimize parallel moves performed before a TailCall by grouping adjacent pushes. This way, we may use a single instruction to push multiple registers at once. However, we also have support for pushing immediates and stack slots for which the benefit is questionnable therefore this patch removes support for them. Concerning immediate pushes, it looks like a mistake since we do not have support for this case in `AssembleMove` so this patch removes it. Furthermore, if we add a test for this case, we see that a `push ip` instruction is generated, effectively pushing whatever was in `ip` at the time instead of pushing a constant. Concerning stack slot pushes, we generate a more or less equivalent sequence of instructions. Finally, grouping floating point pushes is not used anywhere so this patch removes support for this also.

This is the ia32 implementation of the CL https://codereview.chromium.org/2763593002 Original message: [wasm][arm] Add an additional stack check for functions with big frames. Stack overflow checks are typically implemented as part of the TurboFan graph of a function. This means that the stack check code is executed after frame construction. When a frame is too big, though, there may not be enough space on the stack anymore to throw the stack overflow exception after frame construction. With this CL we do an additional stack check before frame construction for functions with big frames. As discussed offline with mstarzinger, I do this change currently only for WebAssembly. This CL contains only the changes for arm. I will do the other platforms in separate CLs.
