Remove trailing junk from IP addresses for sockets

Summary: If IP addresses contain an additional '/' (potentially followed by other
characters) they should all be ignored. For instance prot://1.2.3.4:567/foo
is a connection to 1.2.3.4 on port 567 over protocol prot where /foo is
simply ignored.

Fixes #3154

Change the Profiler constructor to not necessarily force CPU affinity.

Summary: CPU affinity is needed to get monotonic real time clock ticks from rdtsc,
but that effectively disables running multiple threads in server mode.

Some profilers may not need the rdtsc data.

All existing profilers in the code base preserve their previous semantics.

Break regions after FCall & friends when using LLVM

Summary: When using the LLVM backend, we're going to break regions after
bytecodes that use bindcall or something similar. This is intended to be
temporary and for reasons too lengthy to go into here. I also cleaned things up
a little so we actually obey the intent of the EvalJitLLVM runtime option: 1
means Optimize translations only, while >1 means all translations.

Go back to individual cache props for statics

Summary: This diff is a prereq for experimenting with using individual props for instance methods when there are <N of them. It accomplishes a few things:
- Centralize the prop creation logic to make that experiment easier
- Go back to individaul props for statics. Statics almost certainly didn't contribute to the memory regression, and there tend to be only a couple per class so the extra layer was probably a negative
- Eliminates a local when using shared props in favor of emitting the int directly which should make that scenario slightly more efficient.

Wait for clean shutdown on SIGHUP

Summary: HHVM is supposed to do a clean shutdown when it receives SIGHUP -
which it does when using LibEventServer - but with ProxygenServer, it spins off
an additional thread to shutdown queues, leaving the original thread to
re-raise the signal before the queues drain.  Fix this by waiting for the
servers to stop.
