jdelong 9749e6bd54 Initial support for inlining small functions

Sets up the translator analyze pass to create a Tracelet for
the callee at every statically-known FCall.  If the callee has an
appropriate shape (in this diff, it must be a function consisting of
"return $this->foo" for a declared property), we can inline it in
HHIR.  Restructures the IR relating to frames some so we can eliminate
the stores relating to ActRec in this simple case (see the comments in
dce.cpp and hhbctranslator.cpp for details).  Includes partial support
for inlining callees with locals, but it's disabled for now because
they will keep the frame live.
