MIPS: Allocate generator result objects before unwinding try handlers
...
Port r15079 (1ebdfdc6)
Original commit message:
When a generator suspends, it saves its state out to the heap and
unwinds try handlers but doesn't pop anything off the stack. Instead it
relies on no GC happening between the suspend and the return from the
generator. However this was not the case: boxing the result object
could cause GC, which would try to traverse the stack but would
misinterpret words from unwound try handlers as heap objects.
This CL changes to allocate the result objects before the suspend. It
also removes the generators-iteration skip introduced in r15065.

MIPS: Fix LoadIC calling convention.
...
Port r15027 (3ffb343)
Original commit message:
The comments in ic-arm.cc::LoadIC indicated that the receiver should be
both in a register and on the stack. This isn't true in fact: the code
is careful to spill the receiver if needed.
This CL also fixes up a mistaken use of this convention in VisitYield.

use compare nil ic only for non-strict equality. strict-equality only has one check and cannot deopt. should therefore not be part of the stub.
