Update ccc driver
- Use CCC_ECHO to control echoing behavior (default is on, set to ''
or unset to disable)
- Get 'clang','llc','as','cc','ld' executables from environment. 'cc'
and 'ld' are fetched through CCC_CC and CCC_LD respectively -- to
support make CC=ccc -- the others are through their upcased
versions.
- Add CCC_NATIVE mode.
o This uses llc and as to generate native object files; allowing
more drop-in replacement of gcc.
o Disabled by default, but should eventually be default.
o Allow --emit-llvm in CCC_NATIVE mode to override. Essentially
this makes ccc more like a drop in replacement for llvm-gcc.
- Prevent explicit -x <language> options from annoying clang.
