b192870420 Rename LineProfiling to GCOVProfiling to more accurately represent what it 
does. Also mostly implement it. Still a work-in-progress, but generates legal
output on crafted test cases.

93b68b20d4 Add support for line profiling. Very work-in-progress. 
Use debug info in the IR to find the directory/file:line:col. Each time that location changes, bump a counter.

Unlike the existing profiling system, we don't try to look at argv[], and thusly don't require main() to be present in the IR. This matches GCC's technique where you specify the profiling flag when producing each .o file.

The runtime library is minimal, currently just calling printf at program shutdown time. The API is designed to make it possible to emit GCOV data later on.

04317cc618 Implementation of path profiling. 
Modified patch by Adam Preuss.

This builds on the existing framework for block tracing, edge profiling and optimal edge profiling.
See -help-hidden for new flags.
For documentation, see the technical report "Implementation of Path Profiling..." in llvm.org/pubs.

$(libdir), but these ones are "special" because they're part of the the
