005d001719 When a crash signal is delivered do two things: remove all of our
signal handlers to prevent reentrance on unrelated things (a sigabort
where the handle bus errors) also, clear the signal mask so that the
signal doesn't infinitely reissue.  This fixes rdar://6654827 -

faf39c40d4 Add a new 'AddSignalHandler' function to Signals.h that allows
arbitrary functions to be run when a crash happens.  Delete 
RemoveDirectoryOnSignal as it is dead and has never had clients.

Change PrintStackTraceOnErrorSignal to be implemented in terms of
AddSignalHandler.

I updated the Win32 versions of these APIs, but can't test them.
If there are any problems, I'd be happy to fix them as well.

2683c5bc9a If an executable is run through a symlink, dladdr will return the
symlink.  We really want the ultimate executable being run, not
the symlink.  This lets clang find its headers when invoked through

e2ee41d1d1 Don't use plain %x to print pointer values. I had changed it from %p
since %p isn't formatted consistently, but obviously plain %x is wrong.
PRIxPTR with a cast to uintptr_t would work here, but that requires
inconvenient build-system changes. %lu works on all current and
foreseable future hosts.

error that caused it to redirect stderr to stdout too often.

This fix is applied identically to the win32 code as well, but that is
untested.

f2d854e34b Make I/O redirection handling in sys::Program a bit more consistent. No
functional changes. Win32 code is untested, but should work fine.

In the unix variant, rename RedirectFD to RedirectIO and let that function
handle empty and null paths instead of doing that in the caller 3 times. This
is the same as win32 already does it.

In the win32 variant, use Path::isEmpty() instead of checking the resulting
c_str() manually. This is the same as unix already does it.

1a9c18b50d Re-implemented Path::createDirectoryOnDisk (for Unix).
This method allows one to create a directory, and optionally create all parent
directories that do not exist.

The original implementation would require that *all* directories along a path
are writable by the user, including directories that already exist. For example,
suppose we wanted to create the directory "/tmp/foo/bar", and the directory
"/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all
users, the original implementation would work, and create "/tmp/foo", followed
by "/tmp/bar".

A problem occurred, however if one wanted to created the directory
"/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser"
already existed and is writable by the current user. The directory
"/User/myuser" is writable by the user, but "/User" is not. The original
implementation of createDirectoryOnDisk would return with failure since "/User"
is not writable, even though "/User/mysuser" is writable.

The new implementation works by recursively creating parents as needed, and thus
doesn't need to check the permissions on every directory in a path.

c3d03d3f10 cleanup the MappedFile API and comments. This removes and updates
tons of out of date comments (really nothing throws here!) and fixes
some other fairly glaring issues: "size" used to return the size of 
the file *and* change it, depending on how you called it.
