      Reland of Reland of "ARM64: Add NEON support" · fc3f29d3
      martyn.capewell authored 
      This reverts commit c5aad5f2
The CL was reverted due to missing Chromium dependencies.

This commit removes the simulator trace-based tests, and the associated header file dependencies, previously pulled in by DEPS. The NEON support now has only hand-written tests, in test-assembler-arm64.cc. The remaining tests can be added in a later patch.

      Re-reland: Remove register index/code indirection · 5cf1c0bc
      danno authored 
      Previous to this patch, both the lithium and TurboFan register
allocators tracked allocated registers by "indices", rather than
the register codes used elsewhere in the runtime. This patch
ensures that codes are used everywhere, and in the process cleans
up a bunch of redundant code and adds more structure to how the
set of allocatable registers is defined.

Some highlights of changes:

* TurboFan's RegisterConfiguration class moved to V8's top level
  so that it can be shared with Crankshaft.
* Various "ToAllocationIndex" and related methods removed.
* Code that can be easily shared between Register classes on
  different platforms is now shared.
* The list of allocatable registers on each platform is declared
  as a list rather than implicitly via the register index <->
  code mapping.

      Security: disable nontemporals. · a904b569
      jfb authored 
      The operations were available on ARM64 and x86-32 but were unused.

It has been conjectured that nontemporals can be used for rowhammer-like bitflips more easily than regular load/store operations. It is therefore desirable to avoid generating these instructions in the future.

      Remove several grab-bag includes from the v8.h header. · 58109a2c
      mstarzinger authored 
      This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.

Also the number of includes inside the v8.h file has been drastically
reduced. Basically the last missing piece is the inclusion of the big
objects-inl.h file.

This in turn makes many headers follow the IWYU principle.
