fschneider@google.com aa789a7b27 Merge (x & y) == 0 pattern to emit a single test instruction. 
This is based on a previous uncommitted CL by vegorov@
(https://codereview.chromium.org/14251023/).

It is rebased and fixes a bug in the MIPS implementation: BranchOnCondition
requires the comparison result in fixed registers CMPRES1/CMPRES2.

Remove register alias TMP1 (=TMP) and CMPRES (=CMPRES1). It is confusing to
have them around and easy to forget that they are actually the same.

zra@google.com bc42f01492 Adds special case in ARM cpu feature detection. 
Qualcomm Krait CPUs in Nexus 4 and 7 misreport non-support
for integer division. This change checks the model string
reported by /proc/cpuinfo and enables integer division if
we are on one of these CPUs.

Uses the "toolset" feature of gyp to build the dart VM
for ARM, but restricts building of snapshot generation
to the host machine.

For generated source files, it also changes to using
LIB_DIR instead of SHARED_INTERMEDIATE_DIR to avoid
generation of duplicate Makefile rules (gyp doesn't
know that generated source files from toolchains it
thinks are different will be the same.)
