      Revert "Check interrupts in runtime BigInt parser" · ec49e377
      Jakob Kummerow authored 
      This reverts commit 825c61d8.

Reason for revert: Processing interrupts triggers a DisallowHeapAllocation scope failure.

Original change's description:
> Check interrupts in runtime BigInt parser
> 
> The BigInt constructor has quadratic complexity while parsing strings,
> and the input is unbounded. Interrupts should be checked during this
> operation to ensure the host has control over runaway execution.

      [offthread] Change OffThreadIsolate to LocalIsolate · f1589bbe
      Leszek Swirski authored 
      This patch introduces a new LocalIsolate and LocalFactory, which use
LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows
us to remove those classes, as well as the related OffThreadSpace,
OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle.
OffThreadLogger becomes LocalLogger.

LocalHeap behaves more like Heap than OffThreadHeap did, so this allows
us to additionally remove the concept of "Finish" and "Publish" that the
OffThreadIsolate had, and allows us to internalize strings directly with
the newly-concurrent string table (where the implementation can now move
to FactoryBase).

This patch also removes the off-thread support from the deserializer
entirely, as well as removing the LocalIsolateWrapper which allowed
run-time distinction between Isolate and OffThreadIsolate. LocalHeap
doesn't support the reservation model used by the deserializer, and we
will likely move the deserializer to use LocalIsolate unconditionally
once we figure out the details of how to do this.

      Improve toString(radix) for doubles near zero · 348cc6f1
      Michael Mclaughlin authored 
      Currently, Number.prototype.toString(radix) often fails to produce the
least significant bit for doubles near zero. For example, for the
minimum double, 5e-324, toString(2) produces "0". This means that a
user cannot reliably get the exact binary or hexdecimal value of a
double from JavaScript using toString.

This patch makes a slight amendment to the DoubleToRadixCString
function, so that doubles where the gap to the next double is 5e-324
(i.e. doubles less than 2**-1021), are represented exactly in binary and
other power-of-two bases, and close to exactly otherwise. It results
in Number.prototype.toString producing the correct binary value for all
doubles.

      [cleanup] Replace simple typedefs by using · a335f2ae
      Clemens Hammacher authored 
      This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.

This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
     perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'

Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.
