MIPS: Adjust default Heap sizes.

MIPS: Adjust default Heap sizes.

This change decreases the default Heap sizes on MIPS (sets the
same sizes as on Android).

Most MIPS hw has smaller RAM size than 700MB, which can lead
to test failures, if a test does not set the  Heap sizes explicitly
(like cctest/test-mark-compact/MarkCompactCollector).

LGTM.

LGTM with a nit.

src/heap.cc:77: #if defined(ANDROID) || defined(V8_TARGET_ARCH_MIPS)
nit: since a few weeks we quite consistently use V8_TARGET_ARCH_* directly in
#if-conditions, i.e. this would be:

#if defined(ANDROID) || V8_TARGET_ARCH_MIPS

Thanks, fixed!
