Porting PathScale's EKOPath Compiler Suite

[Jung-uk Kim]

I have done preliminary porting work of PathScale's open-sourced 
EKOPath Compiler Suite (https://github.com/pathscale).

http://people.freebsd.org/~jkim/ekopath-devel.tar.bz2

This includes experimental OpenMP support and PathDB.  Unfortuntely, 
PathDB builds fine but just crashes ATM.  Both options are turned off 
by default for now.  Although it seems working fine for many 
non-trivial C/C++/Fortran sources, please do not use it for any 
serious project because I have seen few internal compiler errors and 
crashes.  Be aware of ugly hacks! ;-)

I just wanted to share it now because it was on the WantedPorts list 
on Wiki for a while.  If anyone with more clues want to pick it up 
from here, please feel free.

Cheers,

Jung-uk Kim
