26b6c0ba5d On Mac OS/X, make Process::PreventCoreFiles disable crash reporter for
the process in addition to disabling core file emission.  This speeds up
bugpoint on default-configured macs by several orders of magnitude.

a8e80c5188 Make the removal of files use Path::eraseFromDisk just like it does for
the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes.  This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.

252ad03d7d Change Path::getStatusInfo to return a boolean and error string on an error
instead of throwing an exception.  This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

ff3d80ff7e simple optimization: don't bother calling "exists" (which calls the syscall
"access").  Instead, just let the open call fail if the file doesn't exist.

32f5553c03 For PR787:
Provide new llvm::sys::Program facilities for converting the stdout and
stdin to binary mode. There is no standard way to do this and the available
mechanisms are platform specific. Adjust the bytecode reader and writer to
use these methods when their input is stdin or output is stdout. THis avoids
the problem with \n writing CRLF to a bytecode file on windows.

Patch Contributed by Michael Smith.

   It now just uses isascii to make sure all the characters are legit.
