      Add unittests to keep InstanceType lists in sync · c0282f60
      cbruni authored 
      STRUCT_LIST and INSTANCE_TYPE_LIST are now forced to have the same order
as the InstanceType enum.

Drive-by-fix 1: Move type check and cast functions closer together in objects-inl.h

Drive-by-fix 2: Remove unused instance types SIGNATURE_INFO_TYPE and  TYPE_SWITCH_INFO_TYPE.

      New zone-backed list datastructure to replace ZoneList · 610c0d75
      heimbuef authored 
      Since ZoneLists are essentially non-standard ZoneVectors and have a bad
growing behaviour (ZoneList-allocations make up ~50% of website parse
zone memory) we should stop using them. The zone-containers are merely
a clean-up, with none of them actually better suited to be used with
zones. This new datastructure allows most operations of a LinkedList (
except pop_first and insertAt/removeAt) but uses about the same memory
as a well-initialized ZoneVector/ZoneList (<3% overhead with reasonably
large lists). It also never attempts to free memory again (which would
not work in zones anyway).

The ZoneChunkList is essentially a doubly-linked-list of arrays of
variable size.

Some test-results where I tried storing 16k pointers in different list
types (lists themselves also zone-allocated):

List type                       Zone memory used   Time taken
-----------------------------------------------------------------------
Zone array (for comparison)     131072 B

Ideally initialized ZoneList    131088 B           0.062ms

ChunkZoneList                   134744 B           0.052ms <--new thing

ZoneDeque                       141744 B

ZoneLinkedList                  393264 B

Initially empty ZoneList        524168 B           0.171ms <--right now

ChunkZoneList only push_front   524320 B

      [Turbofan] Add concept of FP register aliasing on ARM 32. · 09ab8e6a
      bbudge authored 
      - Modifies RegisterConfiguration to specify complex aliasing on ARM 32.
- Modifies RegisterAllocator to consider aliasing.
- Modifies ParallelMove::PrepareInsertAfter to handle aliasing.
- Modifies GapResolver to split wider register moves when interference
with smaller moves is detected.
- Modifies MoveOptimizer to handle aliasing.
- Adds ARM 32 macro-assembler pseudo move instructions to handle cases where
  split moves don't correspond to actual s-registers.
- Modifies CodeGenerator::AssembleMove and AssembleSwap to handle moves of
  different widths, and moves involving pseudo-s-registers.
- Adds unit tests for FP operand interference checking and PrepareInsertAfter.
- Adds more tests of FP for the move optimizer and register allocator.

Reason for revert:
Speculative revert due to very strange-looking win/dbg failures

      Land v8-side changes to switch to v8_current_cpu in the GN build. · 6c3aaae9
      dpranke authored 
      This change makes  the architecture that we target generated
v8 code for a property of the current toolchain, rather than a
global setting that applies to every toolchain.

This will allow us to properly build two snapshots for two different
architectures in a single build, which is needed for android
webview/monochrome builds.
