MIPS: Fix for an ARM register allocation bug. · b571bd2c

kmillikin@chromium.org authored Jan 19, 2012

Port r10374 (03bbe39).

Note: the MIPS version was not affected by the bug. This is merely a style cleanup.

Original commit message:
An off-by-one in the register allocator could lead to allocating (and
clobbering) the reserved 0.0 double register.  This required a function with
14 or more live double values.
