goc2c moves here.
parallel builds like old makefiles (-j4).
add clean command.
add banner command.
implement Go version check.
real argument parsing (same as 6g etc)

Windows changes will be a separate CL.

Thanks to Andrey Mirtchovski for tracking this down.

This was broken by CL 5528077 which removed the InsertSemis
flag from go/scanner - as a result, semicolons are now always
inserted and the respective indexer code checked for the
wrong token.

Replaced the code by a direct identifier test.

When slicing a slice, the bounds may be > len as long as they
are <= cap.  Interestingly, gccgo got that wrong and still
passed the testsuite and all the library tests.

This reduces the overhead necessary to work with OS-specific
file details, hides the implementation of FileStat, and
preserves the implementation-specific nature of Sys.

Expressions such as:

  stat.(*os.FileInfo).Sys.(*syscall.Stat_t).Uid
  fi1.(*os.FileStat).SameFile(fi2.(*os.FileStat))

Are now spelled as::

  stat.Sys().(*syscall.Stat_t).Uid
  os.SameFile(fi1, fi2)
