6a91645a84 MIPS: Fix stack frame reconstruction for generators with formal arguments. 
Port r15230 (e2bbe01)

Original commit message:
The formal parameter count was always being treated as an untagged
integer, but it is actually a Smi on ia32 and arm.

c7b3ef0e05 Make sure ExternalCallbackScope is always created when VM state changes to EXTERNAL 
ExternalCallbackScope is used to let CPU profiler know which API callback is being executed. Whenever such callback is called we should create VMState<ETERNAL> and ExternalCallbackScope. This patch fixes several places where VMState<ETERNAL> went without ExternalCallbackScope.

646a34e1e0 Generators: Avoid calling into runtime if operand stack is empty 
This patch makes yield sites save the resume continuation and context
inline.  If the operand stack is empty, we can avoid a call into the
runtime.  This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.

This speeds up the following case by a factor of 3 or so:

  function* until(n) {
    for (var i = 0; i < n; i++)
      yield i;
  }

  function sum(iter) {
    var sum = 0;
    for (var x of iter) sum += x;
    return sum;
  }

  for (var i = 0; i < 10000; i++) sum(until(1000))

Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

f8fc5c443e Allow running mjsunit/manual-parallel-recompile on single-core systems. 
- Add an %IsParallelSupported() builtin function to  make possible to check support of parallel processing from JavaScripts.
- Change the test script that if parallel recompilation is forced on a single core CPU, expect that it won't be recompiled in parallel.
- Change the  JSFunction::MarkForParallelRecompilation() to fall back gracefully if parallel recompilation is not supported.
