af039c53c0 improve the patch for PR1318 to also support grouped options with custom 
handlers (like the pass list).  My previous fix only supported *new* command
line options, not additions to old ones.

This fixes test/Feature/load_module.ll

5247f60d20 rearchitect the registration mechanism used by the command line option stuff. 
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

200c6f9c3d For PR789: 
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

cf8175617d Use a better algorithm for rounding sqrt results. Change the FIXME about 
this to a NOTE: because pari/gp results start to get rounded incorrectly
after 192 bits of precision. APInt and pari/gp never differ by more than
1, but APInt is more accurate because it does not lose precision after 192
bits as does pari/gp.
