Better placement of argument pushing for a few hydrogen call instructions.

Better placement of argument pushing for a few hydrogen call instructions.

Where it's simple to do so (keyed calls, calls to unknown global variables,
calls to local variables and non-property/non-variable expressions), end the
live range of argument subexpressions immediately after the last use of the
expression rather than at the call.

I realize this is kind of ugly.  Feel free to suggest a better but still simple
way to write it.
