The x64 ABI requires that epilogues do not contain code other than stack
adjustments and some limited control flow.  However, we'd insert code to
initialize the return address after stack adjustments.  Instead, insert
EAX/RAX with the current value before we create the stack adjustments in
the epilogue.

r51703 back in 2008 split out all the ObjC Expr subclasses from Expr.h

from Expr.cpp to ExprObjC.cpp. Do so, finally, for readability's sake.

The timeout mechanism has been implemented in python,
so there is no more dependence on external utilities
for timing out an inferior dotest.py process.

Platform-specific bits are implemented for POSIX-like
and Windows platforms.  There is a small class named
ProcessHelper in process_control.py that needs to be
overridden for platforms that fall outside of the
POSIX-like and Windows platforms.

See http://reviews.llvm.org/D13124 for more details.

Add support to the indexed instrprof reader and writer for the format

HHVM calling convention, hhvmcc, is used by HHVM JIT for
functions in translated cache. We currently support LLVM back end to
generate code for X86-64 and may support other architectures in the
future.

In HHVM calling convention any GP register could be used to pass and
return values, with the exception of R12 which is reserved for
thread-local area and is callee-saved. Other than R12, we always
pass RBX and RBP as args, which are our virtual machine's stack pointer
and frame pointer respectively.

When we enter translation cache via hhvmcc function, we expect
the stack to be aligned at 16 bytes, i.e. skewed by 8 bytes as opposed
to standard ABI alignment. This affects stack object alignment and stack
adjustments for function calls.

One extra calling convention, hhvm_ccc, is used to call C++ helpers from
HHVM's translation cache. It is almost identical to standard C calling
convention with an exception of first argument which is passed in RBP
(before we use RDI, RSI, etc.)

PDB files have a lot of noise in them, with hundreds (or thousands)
of symbols from system libraries and compiler generated types.  If
you're only looking for a specific type, this can be problematic.

This CL allows you to display *only* types, variables, or compilands
matching a particular pattern.  These filters can even be combined
with exclude filters.  Include-only filters are given priority, so
that first the set of items to display is limited only to those that
match the include filters, and then the set of exclude filters is
applied to those.  If there are no include filters specified, then
it means "display everything".

The immediate in the load/store should be scaled by the size of the memory
operation, not the size of the register being loaded/stored.  This change gets
us one step closer to forming LDPSW instructions.  This change also enables
pre- and post-indexing for halfword and byte loads and stores.

control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.

All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.

Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.

On some of our benchmarks this change shows about 50% compile time improvement without any noticeable performance difference.
