this cleans up a bunch of code and also fixes several crashes and
miscompiles. More to come unfortunately, this optimization
is quite broken.

abstraction it brings. And also get rid of the atexit() handler, it does not
belong in the lib directory. :-)

(what was I thinking?) and there's also a problem with LCSSA. I'll try again
later with fixes.

having the bitcode writer materialize mdnodes for all the
debug location tuples when writing out the bc file and
stores the information in a more compact form. For example,
the -O0 -g bc file for combine.c in 176.gcc shrinks from
739392 to 512096 bytes.
This concludes my planned short-term debug info work.

source addition. Apparently the buildbots were wrong about failures.

Add some switches helpful for debugging:
-print-before=<Pass Name>
Dump IR before running pass <Pass Name>.
-print-before-all
Dump IR before running each pass.
-print-after-all
Dump IR after running each pass.
These are helpful when tracking down a miscompilation. It is easy to
get IR dumps and do diffs on them, etc.
To make this work well, add a new getPrinterPass API to Pass so that
each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
suitable for dumping out the kind of object the Pass works on.

and the disassembler core which invokes the decoder function and builds up the

materializing an MDNode for every debugloc. don't do that! :)
"clang -g -S t.c" really no longer makes mdnodes for location
tuples now.

representation. This eliminates the 'DILocation' MDNodes for
file/line/col tuples from -O0 -g codegen.
This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.
I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before. Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

<string> include. For some reason the buildbot choked on this while my
builds did not. It's probably due to a difference in system headers.

e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)
