Replace OS::MemCopy with memcpy in typed array initialization.

This is an attempt to fix a weird perf regression on MacOS X 10.6 bot.
Perf regression is not reproducible on MacOS X 10.8.
This difference in memory-copying routines is the only reasonable
difference in the algorithm. We should try and see.

ARM: Fix register misuse bug in Allocate().

The bug is triggered if flags contains DOUBLE_ALIGNMENT and the
object_size is not an ARM immediate value. In this case, the code
for DOUBLE_ALIGNMENT uses the scratch2 register, which is aliased
to obj_size_reg containing the object_size.

Instead of pre-loading the object_size, which is difficult since
we are out of registers here, we simply generate a non-empty
sequence of add instructions for the addition of the constant
object_size (carefully handling possible overflow in each step).

Also turn static ASSERT into STATIC_ASSERT in Allocate().

Instance-type-related fixes and cleanup.

Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.

Deprecate self and total time getters and total sample count getter on CpuProfileNode

All of these values are derived from the self samples count and there is no need to evaluate them in v8 when clients can do that when needed on their side.

Also added unsigned GetHitCount() which should be used instead of double GetSelfSamplesCount(). I'm going to deprecate the latter one once Blink has switched to GetHitCount.

MIPS: Patch to enhance the source code line information for profiler.

Port r16114 (2d1bf399)

Original commit message:
This patch is to enhance the source code line information for profiler.

For the Hydrogen compilation, most of the source code line information
is not copied from the HInstruction the to corresponding LInstruction.

This patch defines one PositionBits field for LInstruction and copies the
sorce code position value from the HInstruction.

When Generating the native code, we use RecordPosition(..) function to
write LInstruction's position value to position recorder.

MIPS: Optimize DoCheckMaps.

This simple change moves the Deoptimize call into the Deopt table
where it belongs, and shortens the inline map-check.

Gives a surprisingly large performance gain, around 4% on Octane.
