      Enable component builds for fuzzers · 22606f0c
      jgruber authored 
      V8 is collecting a growing amount of fuzzers, all of which take substantial
space on the bots and in chromium build archives. This CL improves that
situation by allowing component (shared library) builds for almost all fuzzers.

The parser fuzzer is handled as an exception since it would require exporting a
large number of additional functions.

A component build results in about a 50-100x improvement in file size for each
fuzzer (~50M-100M to around 1.1M).

      [Turbofan]: Use new MachineTypes in access-builder. · 56429fc1
      mvstanton authored 
      Introduced MachineType::TaggedSigned() and TaggedPointer().

The idea is to quit using the representational dimension of Type, and
instead encode this information in the MachineRepresentation (itself
lightly wrapped in MachineType, along with MachineSemantic).

There are three parts to the whole change:

1) Places that set the machine representation - constant nodes, loads nad
   stores, global object and native context specialization.

2) Places that propagate type/representation - this is representation
   inference (aka simplified lowering). At the end of this process we
   expect to have a MachineRepresentation for every node. An interesting
   part of this is phi merging.

3) Places that examine representation - WriteBarrier elimination does this.
   Currently it's looking at the Type representation dimension, but as
   a part of this change (or in a soon-to-follow change) it can simply
   examine the MachineRepresentation.

      [turbofan] Rename floating point register / slot methods. · 8c8600db
      bbudge authored 
      Renames IsDouble* predicates to IsFP*.
Adds specific IsFloat*, IsDouble*, and IsSimd128* predicates.
Adds specific GetFloatRegister, GetDoubleRegister, and
GetSimd128Register methods.

This is mostly a mechanical renaming of IsDouble* to IsFP* methods.

This shouldn't change code generation at all. All fp registers are still
treated as double registers.

      [turbofan] Make MachineType a pair of enums. · bb2a830d
      jarin authored 
      MachineType is now a class with two enum fields:
- MachineRepresentation
- MachineSemantic

Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.
- Phi and Select nodes only refer to representations.

      [turbofan] Fix tail call optimization. · d21de2a4
      bmeurer authored 
      Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.
