f68e24ad46 Revert "[test] Initial import of an emscripten test suite." 
This reverts commit bb346227db because it
adds a lot of overhead without significantly increasing our test
coverage. We need a different approach to deal with this.

Reason for revert:

580d66bcda [strong] checking of this & super in constructors 
R=dslomov@chromium.org, marja@chromium.org
BUG=v8:3956
LOG=N

Enforces for constructors that
- the only use of 'super' is the super constructor call
- the only use of 'this' is a property assignment
- both of these must happen at the top-level of the body
- 'this' may only be assigned after the 'super' call
- 'return' may only be used after the last assignment to 'this'

Not yet working for arrow functions (there might be deeper bugs with those).

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.
