This adds the basics necessary to support float32 operations in TurboFan. The actual functionality required to detect safe float32 operations will be added based on this later. Therefore this does not affect production code except for some cleanup/refactoring. In detail, this patchset contains the following features: - Add support for float32 operations to arm, arm64, ia32 and x64 backends. - Add float32 machine operators. - Add support for float32 constants to simplified lowering. - Handle float32 representation for phis in simplified lowering. In addition, contains the following (related) cleanups: - Fix/unify naming of backend instructions. - Use AVX comparisons when available. - Extend ArchOpcodeField to 9 bits (required for arm64). - Refactor some code duplication in instruction selectors.

Basically recognize certain x < y ? x : y constructs and turn that into Float64Min/Float64Max operations, if the target machine supports that. On x86 we lower to (v)minsd/(v)maxsd.

Provide an intrinsic %MathFloor / %_MathFloor that is used to optimize both Math.ceil and Math.floor, and use the JS inlining mechanism to inline Math.ceil into TurboFan code. Although we need to touch code outside of TurboFan to make this work, this does not affect the way we handle Math.ceil and/or Math.floor in CrankShaft, because for CrankShaft the old-style builtin function id based inlining still kicks in first. Once this solution is stabilized, we can use it for Math.floor as well. And once that is settled, we can establish it as the unified way to inline builtins, and get rid of the specialized builtin function id based inlining at some point. Note that "builtin" applies to basically every piece of internal JavaScript/intrinsics based code, so this also applies to the yet to be defined JavaScript based code stubs and handlers.

Revert of Externalize deoptimization reasons. (patchset #7 id:120001 of https://codereview.chromium.org/874323003/) Reason for revert: This CL breaks RelocInfo::INTERNAL_REFERENCE (and maybe others that come after DEOPT_REASON), which is currently (mostly) unused on tip-of-tree, but will be used for jump tables soon(ish) and should therefore work. It seems to be a problem with implicitly assumptions about the number of reloc info modes. Needs further investigation.

This CL updates RelocInfo update operations and set_target_address_at to enable skipping of the icache flush if it going to be batched up later. Code::CopyFrom and Code::Relocate are modified to avoid individual icache flushes since the whole code area will be flushed after the reloc info is updated. These changes reduce a regression when enabling the OOL constant pool on Arm, since this change can cause MovT/MovW instructions for relocatable targets if the constant pool is full. Scores for Mandreel latency on a Nexus 5: - OOL CP disabled: 3533 - OOL CP enabled, without this CL: 1825 - OOL CP enabled, with change: 3015 R=rodolph.perfetta@arm.com, ulan@chromium.org Review URL: https://codereview.chromium.org/284153004 git-svn-id: https://v8.googlecode.com/svn/branches/bleeding_edge@21380 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Traditionally, we cross compile a snapshot iff the serializer is enabled. This will change in the future. Changes: - CpuFeatures probing is done once per process, depending on whether we cross compile. - CpuFeatures are consolidated into the platform-independent assembler.h as much as possible. - FLAG_enable_<feature> will only be checked at probing time (already the case for ARM). - The serializer state is cached by the MacroAssembler. - PlatformFeatureScope is no longer necessary. - CPUFeature enum values no longer map to CPUID bit fields.
