Change 'Parse error' to three more informative messages.
...
Replace the 'unable_to_parse' key used in three places with three difference keys.
Provide three more informative and less ambiguous error messages in place of 'Parse error'.
Add three test/message cases to cover the new messages.

Add support for yield expressions
...
This CL extends the generator suspend and resume implementation to
capture values on the operand stack.
It factors out some helpers to measure and access the operand stack into
the JavaScriptFrame class. It also refactors the suspend and resume
helpers to avoid handle allocation.

Fix yield inside with
...
This patch makes it so that suspending generators always saves the
context. Previously we erroneously assumed that if the operand stack
was empty, that the context would be unchanged, but that is not the case
with "with".
Fixing this brought out an interesting bug in the variable allocator.
Yield inside with will reference a context-allocated temporary holding
the generator object. Before the fix, this object was looked up in the
with context instead of the function context, because with contexts were
not being simulated during full-codegen. Previously this was OK as all
variables would be given LOOKUP allocation instead of CONTEXT, but the
context-allocated temporary invalidated this assumption. The fix is to
simulate the context chain more accurately in full-codegen.
