2c37146bfa Treat WASM_FUNCTION frames as stubs.
This is "more correct" than WASM_FUNCTION falling through the switch
over code types and using the marker on the stack which contains a bogus
value.

In the long run, there will be two kinds of WASM-related frames: frames
that cross the JS/WASM border, and internal WASM_FUNCTION frames. This
will necessitate a new StackFrame::Type, since the first kind of frame
must treat its parameters as tagged values and the second definitely
should not.

09b44428e4 [runtime] First step to sanitize regexp literal creation.
This is the initial step towards refactoring the regexp literation
creation code to make it less obscure and more similar to the mechanism
we use to create array and object literals.  There's now a new runtime
entry %CreateRegExpLiteral with the same interface as the entries for
array and object literals, except that we still pass the flags as
string.

Instead of embedding the hand written native to clone JSRegExp instances
we now have a FastCloneRegExpStub, which behaves similar to the other
FastCloneShallowArrayStub and FastCloneShallowObjectStub that we already
had.

240571d768 X87: [turbofan] Add general support for sp-based frame access.
port 5166987369 (r32234)

  original commit message:
  Some highlights of this CL:
  * Refactor the mutable state out of Frame into FrameAccessState,
    which is maintained and updated during code generation to
    record whether sp- or fp-based frame access is currently active
    and how deep the stack on top of the frame is.
  * The operand resultion in linkage.cc now uses FrameAccessState
    to determine how to generate frame-accessing operands.
  * Update all platforms to accurately track additionally pushed
    stack slots (e.g. arguments for calls) in the FrameAccessState.
  * Add a flag, --turbo_sp_frame_access, which forces all frame
    access to be sp-based whenever possible. This will likely never
    be used in production, but for testing it's useful in verifying
    that the stack-tracking of each platform maintained in the
    FrameAccessState is correct.
  * Use sp-based frame access for gap resolving before tail
    calls. This will allow for slightly more efficient restoration
    of the frame pointer in the tail call in a later CL.
  * Remove most ad hoc groping into CallDescriptors to
    determine if a frame is needed, instead consistently use
    predicates like needs_frame(), IsCFunctionCall() and
    IsJSFunctionCall().

b6e9f625c1 [es6] Self-assignment in a default parameter initializer should throw
The first bug was that there are two different "initialization positions"
passed into PatternRewriter::DeclareAndInitializeVariables, and we weren't
setting them all properly for this case.

After further code review, it became clear that we weren't even recording
the correct position (the end of the initializer expression).

The combination of those two bugs caused the hole check elimination code
in full-codegen to skip emitting a hole check.

This patch takes care of both of those things. A follow-up will try
to reduce the number of "initializer positions" we track in the
variable declaration code.

ceb92ebfdf Disallow destructuring in legacy sloppy for-in loop parsing
For web compat reasons, we support an initializer in the declaration
part of a for-in loop. But we should disallow this for destructured
declarations (just as we do for lexical declarations). In fact, without
disallowing it, we crash.

Also fix up the PreParser to have the same restrictions here as the parser
(the lexical check was missing there), verified by running the message tests
with --min-preparse-length=0.

In fixing the logic I've also cleaned up the code a bit, removing the
only-called-once DeclarationParsingResult::SingleName method.

64efa2a904 [machine-operator-reducer] fix float truncation
Don't replace `TruncateFloat64ToInt32(RoundInt64ToFloat64(value))` with
`value`. Generally, `value` may have a range bigger than the one that
could fit into Int32. Replace it with `TruncateInt64ToInt32(value)`
instead, and only if the `value` fits into Float64 without precision
loss.

Add missing mjsunit test for 52bit multiplication/division optimization
that has landed in refs/heads/master@{#31899}.

c3e6048cde We can avoid spilling live ranges with spill ranges when we have
sufficient physical registers for all the virtual registers.

This should come in handy for frame elision. There, I noticed that even
for very small functions (==very few virtual registers), because we spill
the context/function marker ranges, we lose the frame elision
opportunity.

There is a subsequent change needed to fully help frame elision -
decoupling spilling of context & function marker from prologue.

1b1db13549 [runtime] Pass closure to %CreateArrayLiteral and %CreateObjectLiteral.
Change the runtime entries and their associated code stubs for object
and array literal creation to take the closure instead of the raw
literals pointer. This is way easier to deal with (and cleaner) in
TurboFan.

turned out to be dangerous, because it cannot be used without exporting
