97585ab8b5 ARM64: Avoid iterating through all unresolved branch infos when many are pending. 
Instead, inspect the label chain and delete pending information for every branch

b0938269dc ARM64: Fix EnsureSpace to not emit pools. 
The EnsureSpace scope must not trigger any code emission, so it should only grow
the buffer, and not check for pools.

a9db3bc868 Some tests and simplified TransitionArray copying 
Tests for verifying that we deal correctly with shrinking transition
arrays while allocating a copy of one.

Also, we can rely on a transition array only shrinking and not
disappearing during gc while copying one.

ed1d232d5d Parser cleanup: PreParser doesn't need to produce symbol data any more. 
State of the art:
- Chromium doesn't do a separate preparsing phase any more.
- We start parsing with Parser, and when it sees a lazy function, it falls back
to PreParser for that function.
- The symbol data should contain symbols which are *outside* lazy functions.
- So Parser should always produce symbol data, and PreParser should never.
- Because it's this simple now, we don't need to keep track of "should
produce symbol data" (i.e., whether we're inside a lazy func or not).

9cf3909975 Track field types. 
This is an initial step towards tracking the exact types instead of just the representations of fields. It adds support to track up to one map of heap object field values, eliminating various map checks on values loaded from such fields, at the cost of making stores to such fields slightly more expensive.

stubs are treated as weak references by the marking visitor.

During generation of an IC stub with a weak map, the stub is appended to the

code array are invalidated by setting embedded maps to undefined.

b61696dd95 ARM: Do not set FPSCR when converting to clamped uint8 
Setting the FPSCR flags is expensive on some CPUs. Get rid of repeated
setting of the FPSCR by relying on the correct default flags being set
when doing uint8 clamping. Also use vcvt_u32_f64 instead of vcvt_s32_f64,
which enables removing the check against zero (vcvt_u32_f64 will clamp to
zero).

To be on the safe side, add asserts to check that the VFP rounding mode
flags are set to default as expected.

This increases performance of a hot loop repeatedly setting
Uint8ClampedArray values on some CPUs by as much as a factor of 12.

fd988331ea There is no definition for HArgumentsObject, so LDummyUse confuses the register allocator. I have recently made similar fix for HCapturedObject (see https://codereview.chromium.org/222283002/).

74d49a1e7e ARM64: Preserve x8 and x9 when necessary. 
Fix a couple of places were x8 and x9 are excluded from lists of saved
registers. These are caller-saved registers, so C code can corrupt them.

x8 and x9 were originally reserved for debug code in the ARM64 port, so
we didn't bother preserving them, but they are now normal allocatable
registers.
