5b84600196 Stub out a Path::GetMainExecutable call to find the path to the
main executable of a program.  This needs to be implemented on windows.

e35e9d07b0 Use the stat information in the Path object, if it is already obtained. This
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

4269ae1274 For PR789:
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

to the inode number on Unix and something far less unique on Windows. The

b1b1f483ed 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.

ec2ce4eaab Add a note about how the "isFile" check in Path::eraseFromDisk prevents
the erasure of non-file paths like /dev/null.

f4c7ceebaf 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.

4854a2a120 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.
This reduces the # syscalls executed.
