Log: 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.
