fa2287fa96 Force eager compilation of parenthesized functions.
This makes the compiler use eager compilation for function literals that
are parenthesized. We consider this to be a hint that the function will
be called immediatly and hence try to avoid parsing it twice. The parser
already respects this heuristic.

1d0f872ef9 Fix full code generator to not use --debug-code if it is in
mksnapshot or a VM that is booted from a snapshot.  --debug-code
can still have an effect on stub and optimized code and it still
works on the full code generator when running without snapshots.

The deoptimizer generates full-code-generator code and relies on it having
the same layout as last time.  This means that the code the full code
generator makes for the snapshot should be the same as the code it makes
later.  This change makes the full code generator create more consistent
code between mksnapshot time and run time.

This is a bug fix and a step towards making the snapshot code more robust.

2f43f5e9d7 MIPS: Rename "mips" arch to "mipsel" in the GYP build.
In the traditional MIPS naming scheme, "mips" is used for
big-endian mips and "mipsel" is used for little-endian mips.
In V8 the "mips" build is little-endian, so the "mips" target is
renamed to "mipsel" to be compliant with the traditional MIPS
naming scheme.

This change is also required for supporting the Chromium project on MIPS.

d7a5b7d5e2 Separating transitions from descriptors.
In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.

The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.

Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.

c22c7054f2 Add Makefile targets for running tests on Android.
This allows to run tests on the attached Android device using
> make android.check
> make android.debug.check
> make android.release.check
> ANDROID_V8=/data/local/v8 TESTJOBS=-j4 make android.release.check -j10

Tests and binaries are copied to device location specified by the ANDROID_V8
variable and then tests are executed using the 'adb shell' program.
