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.

The generator object methods "next", "send", and "throw" now
include some inline assembly to set up a resumed stack frame. In some
common cases, we can just jump back into the frame to resume it.
Otherwise the resume code calls out to a runtime to fill in the operand
stack, rewind the handlers, and possibly to throw an exception.

Generators can resume
...
The generator object methods "next", "send", and "throw" now
include some inline assembly to set up a resumed stack frame. In some
common cases, we can just jump back into the frame to resume it.
Otherwise the resume code calls out to a runtime to fill in the operand
stack, rewind the handlers, and possibly to throw an exception.

...
CodeEntry* is always NULL for SharedFunctionInfo entries in the CodeMap. Take this into account when printing the map.
Drive-by: removed CodeEntry::shared_id() which is never called.

Replace qsort with std::sort.
...
std::sort is a template, so it can be inlined more aggressively. Also, it's
O(n log n), while libc's qsort is O(n^2)
