bb346227db [test] Initial import of an emscripten test suite. 
These tests are based on individual tests from the Emscripten benchmark
suite, which are used to test Emscripten itself. We adopt them to test
asm.js code paths in V8.

636cb4f365 Factor formal argument parsing into ParserBase 
This commit is a precursor to making lazy arrow function parsing use
similar logic to function(){} argument parsing.

Originally landed in these three CLs:

  https://codereview.chromium.org/1078093002
  https://codereview.chromium.org/1083623002
  https://codereview.chromium.org/1083953002

These were rolled out due to a performance regression on CodeLoad.  This
patchset will fix that by avoiding creation of a DuplicateFinder in the
full parser.

cc838be4b6 Don't assert that no incremental marking happened during a non-incremental GC 
If a scavenge is triggered during the GC (via a weak callback or the GC
prologue/epilogue), and another mark-compact is triggered (via the same
unfortunate code path), we end up doing some incremental steps.

This is first step towards adding V8 heap statistics to the memory
tracing infrastructure. For being able to get useful memory number into
the memory dump, v8 needs to provide an external api needs to obtain
more information about the heap. So, this Cl extends the api to give
information about the memory allocated and used in the spaces.
