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/).

Make sure that ranges are not accessed after range analysis. Remove HValue::PrintRangeTo.

The ranges are simply wrong after range analysis, and we should only rely on computed flags.

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.

Make maps in monomorphic IC stubs weak.

Maps in monomorphic Load, KeyedLoad, Store, KeyedStore, and CompareNil IC
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
dependent code array of the map. When the map dies, all stubs in its dependent
code array are invalidated by setting embedded maps to undefined.
