      Intl.DateTimeFormat: throw RangeError for non-finite input · 831bc233
      Jungshik Shin authored 
      intl.js throws an exception when datetime-value to format is
Infinity or NaN, but there was a way to thwart the check.

Moreover, intl.js and runtime-intl.cc have unnecessary conversions
of 'Number->Date->Number'. I removed the unnecessary conversion
and made 'Number' be passed to %InternalDateFormat.  With this
streamlining, the work-around mentioned above does not work
anymore.

Add a check in runtime_intl.cc for Infinity/NaN and throw a
RangeError.

Add invalid-time test for invalid datetime-values passed to
Intl.DateTimeFormat.format().

Bug: chromium:774833
Test: intl/date-format/invalid-time.js

      Revert "[turbofan] Load elimination prunes control flow based on instance type." · 8f09a751
      Jaroslav Sevcik authored 
      This reverts commit 71bcc1d9.

Reason for revert: Regresses Octane/Box2D, among other things.

Original change's description:
> [turbofan] Load elimination prunes control flow based on instance type.
> 
> Changes:
> - introduce the notion of unreachable abstract states.
> 
> - reconnect unreachables states to runtime abort in effect phis (so that
>   the merged states are not polluted by unreachable branches while
>   preserving SSA).
> 
> - mark states with failed map checks, unreachable map guars as unreachable.
> 
> - add instance type to AbstractMaps, only invalidate instance type on
>   mismatched effect merges.
> 
> 
> This results in 2-3% improvement on ARES/ML steady state.

      HTMLCollection and NodeList have InstanceType

of GetAlignedPropertyFromInternalField. This slows down the performance
of indexedPropertyGetter for both types, which are very commonly used
in websites.

      The regression sneaked in when unifying the marking visitors in
4b42656d. The concurrent marker keeps a
local live byte count per page so it is safe to rely on non-atomic

      [Cleanup][Interpreter] Move feedback slot allocation to bytecode generator · ed592eb0
      Ross McIlroy authored 
      Moves the feedback vector slot allocation out of ast-numbering and into
bytecode generation directly. This has a couple of benifits, including reduced
AST size, avoid code duplication and reduced feedback vector sizes in many cases
due to only allocating slots when needed. Also removes AstProperties since
this is no longer needed.

AstNumbering is now only used to allocate suspend ids for generators.

      [runtime] Refactor initialization of in-object property count of a map. · 2a3cab7a
      Ulan Degenbaev authored 
      This patch moves initialization of inobject_properties and
unused_property_fields of a map to the construction time of the map.

Map::AppendDescriptor now properly decrements unused_property_fields
and thus maintains the invariant for property field counters.
