Gllvm Versions Save

AUDIT log level plus the odd cosmetic change.

A fix for the misinterpretation of the naked -W and -w flags, fixed by @woodruffw. Does wllvm suffer the same issue? I should check.

Improvements to its behavior on FreeBSD, recognizing the extensions .pico and .nossppico and treating them as the object files they are. Improvements to the dependency command line switches, so they do not get confused as inputs. Use of the debug/elf and debug/macho packages to recognize file types, and use this capability to have a fallback when simple minded (but fast) pattern matching doesn't work.

Improved support for builds that use clang's link time optimization. Added some flags as usual. Beefed up the parsing so that it handles (non-nested) -Wl,start-group ... -Wl,end-group command line options. Added an undocumented executable gparse which just parses the command line as would gclang or gclang++ and just prints the result rather than acting upon the input.

Strict mode added to get-bc by @woodruffw

Added support for LTO style flags in the bitcode generation phase.

Fixes for issues number 30 and 31, as well as a request to push this release out.

Roughly the same as wllvm's 1.2.7. Just a few minor fixes.

Argument parsing fixes as usual. sysroot, pthread, and fuse-ld.

Various fixes from large stress builds, plus repairing some self-inflicted wounds on mac os x.
