7f429e62c3 [Arm]: Simplify compile-time Arm feature detection. 
Simplify the compile time feature detection on Arm:
 - Define CAN_USE_XXX definitions unconditionally for all target/host
   toolchain combinations
 - Rename arm_test / ARM_TEST to arm_test_noprob / ARM_TEST_NO_FEATURE_PROBE
 - Don't set ARM_TEST_NO_FEATURE_PROBE implicitly on the simulator to make
   make simulator / native more consistent
 - Unify CpuFeatures::PrintTarget for simulator and native builds
 - Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
   the default for arm_fpu=default)
 - Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
    to ensure we have probed features before printing them.

1b080a76c1 [Arm] Various cleanups to the Arm assembler backend. 
A couple of cleanups to the Arm backend to enable support of extended
OOL constant pools in a following CL.

 - Remove instruction pattern extern const's and replace their use with IsXXX()
   functions.
 - Do calculation of the target address of a load from constant pool in one
   place.
 - A couple of other small cleanups.

ec22430733 ARM64: updated literal pool implementation. 
Currently the literal pool implemetation is inherited from the arm 32-bit port
and it shares the same limitations: 4k of range and 1000 entries max. In arm64
the load literal has a 1MB range giving us more flexibility.

Immutable entries are now shared.

1ef52275d5 Set host_arch to ia32 on machines with a 32bit userland but a 64bit kernel. 
I don't know if there are any v8 bots with that configuration, but it seems
like a good idea to have v8 be consistent with chromium and nacl here, so that
this works fine if such a bot is ever set up.

This is similar to https://codereview.chromium.org/342493002/ , but with a
detect_v8_host_arch.py script that handles the additional machine types that
standalone.gypi used to handle.

736a17f8f4 ARM: Avoid duplicate vmla when merging vmul and vadd 
Avoid generating duplicate vmla instructions for vmul/vadd sequences where the
vmul has more than one use.

For example: function f(a, b, c) { return (a * b) + c + (a * b); }

Previously, this would produce a vmul for the subexpression (a * b), then vmla
for (a * b) + c, then vmla for (a * b) + [(a * b) + c].

Now it produces vmul, vadd, vadd, as expected.
