      [coverage] Handle repeated CoverageInfo deletions · e567e5ca
      jgruber authored 
      Debug::ClearCoverageInfo may be called multiple times, for example
whenever coverage mode is switched to BestEffort. When encountering a
DebugInfo that does not have a CoverageInfo attached, simply do nothing
instead of failing a DCHECK.

      [heap] Scavenger: Fix benign race in LayoutDescriptor access · bb840f4f
      Michael Lippautz authored 
      We need to write the slot with a relaxed write. No additional barrier is
needed because the new object has been published using Release_CAS and
reading either value is fine (as long as all initializing stores have
been published).

      [wasm] Consolidate function table representation. · 4a45f35f
      Mircea Trofin authored 
      This CL avoids the need to reference the function tables (and signatures)
as either fixed arrays or vectors, preferring vectors.

The only place we need fixed arrays is on the compiled module, to support
serialization. When we move off the GC heap, we'll also move away
from fixed arrays in that last case.

The CL aids with getting wasm of the GC heap, by reducing the places 
and representations we'll need to change  when changing the way we 
reference fixed tables.

      Fix missing (function decoding time/function size) UMA metrics. · 23e882eb
      Karl Schimpf authored 
      Check for these UMA stats were in functions only used for testing. Moved the
checks to code inside module decoding.

Note that the module decoder is used both to validate and generate the
intermediate (turbofan) graph of function bodies.  This CL assumes
that the validation phase (of function bodies) is the correct place to
track decoding time.
