[LLVMdev] [API CHANGE (on trunk)] raw_fd_ostream defaults to overwrite

[Dan Gohman]

Hello,

The following describes an API change on trunk. The change is not in  
the 2.6 branch.

The raw_fd_ostream class now defaults to overwriting its output file,  
and the
F_Force flag which was introduced only recently is gone.  There's a  
new F_Excl flag to
support users wanting the behavior of returning an error if the file  
exists, though no one
actually appears to want this.

Accompanying this is a change to the command-line tools. The tools  
will now overwrite
their output files unconditionally, without needing the -f option.
