Original commit message:
Properly handle holes following spreads in array literals
Before this change, the spread desugaring would naively call
`%AppendElement($R, the_hole)` and in some cases $R would have
a non-holey elements kind, putting the array into the bad state
of exposing holes to author code.
This patch avoids calling %AppendElement with a hole, instead
simply incrementing $R.length when it sees a hole in the literal
(this is safe because $R is known to be an Array). The existing
logic for elements transitions takes care of giving the array a
holey ElementsKind.

Original commit message:
Reduce the memory footprint of expression classifiers
This patch attempts to reduce the (stack) memory footprint of
expression classifiers. Instead of keeping space in each
classifier for all possible error messages that will
(potentially) be reported, if an expression turns out to be
a pattern or a non-pattern, such error messages are placed in
a list shared by the FunctionState and each classifier keeps a
couple of indices in this list. This requires that classifiers
are used strictly in a stack-based fashion, which is also in line
with my previous patch for revisiting non-pattern rewriting.

Original commit message:
For global object property cells, we did not check that the map on the
previous object is still the same for which we actually optimized. So
the optimized code was not in sync with the actual state of the property
cell. When loading from such a global object property cell, Crankshaft
optimizes away any map checks (based on the stable map assumption),
leading to arbitrary memory access in the worst case.
TurboFan has the same bug for stores, but is safe on loads because we
do appropriate map checks there. However mixing TurboFan and Crankshaft
still exposes the bug.

Original commit message:
Don't skip hole checks inside patterns in parameter lists
Previously, b6e9f625c17f3a688139426771e2cb34fbdcb46e fixed self-assignment
in parameters to throw. But it failed to deal with the case of
destructuring with defaults. This patch extends that previous approach
to always treat the end of a parameter as its initializer position,
whether it has an initializer or not.
This is the minimal change to make it easy to merge; a follow-up
will rename the field of Parameter from "initializer_end_position"
to "end_position".

[heap] Properly propagate allocated space during new space evacuaton in
MC
New space evaucation in MC supports, similar to scavenges, fall back
allocation in old space.
For new space evacuation we support sticky and non-sticky modes for
fallback. The sticky mode essentially removes the capability to allocate
in new space while the non-sticky mode only falls back for a single
allocation.
We use the non-sticky mode for allocations that are too large for a LAB
but should still go in new space. When such an allocation fails in new
space, we allocate in old space in non-sticky mode as we would still
like to reuse the remainder memory in new space. However, in such a case
we fail to properly report the space allocated in resulting in a missed
recorded slot.

Original commit message:
S390:Update inline asm constraint in test-platform
The GetStackPointer() routine in test-platform uses an inline
assembly code to store the current stack pointer value into a static
variable sp_addr. The existing asm code for S390 uses an ST/STG
instruction, with the memory operand associated with the general ('=g')
constraint to sp_addr.
On GCC 4.8.5, the GCC compiler got confused and treated sp_addr as
an integer operand instead of memory operand, resulting in a store
being emitted that writes to an invalid meory location.
Given the specific store instructions being inlined here, we should
restict the sp_addr operand to explicitly be a memory operand using '=m'
instead of '=g'.
