Use first position in LAllocator ordering heuristic.

This changes the tiebreaker for LAllocator's ordering heuristic of
live ranges to use the first use position instead of the first hinted
use position. Searching for the first hinted position introduces

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.
