997ce05289 Fix for failing asserts in HBoundsCheck code generation on x64: use proper cmp operation width instead of asserting that Integer32 values should be zero extended. Similar to chromium:345820.

6115a006fd Bugfix for 349874: we incorrectly believe we saw a growing store 
When we set an out of bounds array index, the index might be so large that
it causes the array to go to dictionary mode. It's better to avoid
"learning" that this was a growing store in that case.

This fix also partially reverts a fix for bug 347543, as this fix is
comprehensive and satisfies that repro case as well (partial revert of
v19591).

b9e0b87a5a Clear optimized code cache in shared function info when code gets deoptimized. 
This adds a pointer to the shared function info into deoptimization data of an optimized code. Whenever the code is deoptimized, it clears the cache in the shared function info.

This fixes the problem when the optimized function dies in new space GC before the code is deoptimized due to code dependency and before the optimized code cache is cleared in old space GC (see mjsunit/regress/regress-343609.js).

This partially reverts r19603 because we need to be able to evict specific code from the optimized code cache.

b1ffc7901f A JSArray may have a filler map in the elements pointer. 
We already have code that expects this, but incorrectly asserted that the
filler map case would never happen when allocation folding is turned on.
However, even folding has it's limits, bailing out of continued folding
when the object size grows too large. Therefore, it's a general problem
when verifying JSArray objects, that we might encounter a filler map
in elements().

Discovered by ClusterFuzz crbug 347903.

call/field access handling.

The change also fixes the same thing for polymorphic named field
access even thourgh the field access is probably safe in practice
(because it cannot deoptimize). It is better to keep all our simulates
in sync with full codegen.

7b7e3658f7 Don't propagate information through phis in loop headers. 
To properly do this, we'd have to iterate over CompareMaps (and their bodies) handling phis, until we have learned enough to decide which paths can be taken. For now, just disable learning from phis in loop headers.
