- add volatile to asm instead
- add compiler barriers throughout
- tweak asm for x86Gcc_compare_exchange()
- remove unnesessary CPU fences from x86Gcc_atomic_thread_fence()

Merge remote-tracking branch 'remotes/origin/master'

* remotes/origin/master:
  whitespace cleanup; convert tabs => 8 spaces, remove trailing spaces
  [BUGFIX] an accidental use of program options was included even if it wasn't   enabled leading to an error with cmake-2.8.  Check properly, and fatal   error out if Lintel thinks it's enabled but the needed library can't be found.
  Cleanup to build on Ubuntu 12.04.
  Changes necessary to get compilation working with llvm 3.1 + boost 1.49
- implement atomic_signal_fence
- improve documentation
Disable no-strict-aliasing pragmas for GCC 4.4 and below

The pragmas which control aliasing for the strict-aliasing-unsafe code portions tickles an internal
compiler bug on GCC 4.4; fortunately it seems that GCC 4.4 and below don't actually optimize
aggressively enough that fno-strict-aliasing should be required for this code.
add AtomicCounter typedef for backward compatibility

Added option to serial perform the diffing and commit message editing; this
emulates the old behavior, and is necessary for people who can't use X
readily.

Initialized counter to 0 in the Atomic class for compatibility with
older compilers. Prevents error where counter is som arbitrarily determined
number.

Minor fix to AtomicCounter and Marsaglia Random for initializing things

C++0x introduces std::hash (amongst other hash related functions and templates).
This caused a template error in the hashType() definition for std::pair.
This change fixes that.
