movl 0(%rax), 0(%edx)

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

This greatly simplifies the interfaces and interactions. The lifetime of
the TextDiagnostic object forms the 'session' over which we attempt to
condense and deduplicate information in diagnostics.

helpers into the implementation file, and only the public interface
doxyments into the header. If folks have strong opinions about this type

making it accessible to anyone from the Frontend library. Still a good
bit of cleanup to do here, but its a good milestone. This ensures that
*all* of the functionality needed to implement the DiagnosticConsumer is

static functions.

diagnostics to control suppression of redundant information. It now
follows the same model as all the other state, and has a bit more clear
semantics.

This is making the duality of the state a bit annoying, and I've added
a FIXME to resolve it. The problem is that I need to lift the
TextDiagnostic up into an externally visible layer before that can
happen.

Place static initializers on linux into the ".text.startup" section, so the linker can group them together for performance.

This only has an effect with fairly new binutils (2.21.51 or later). Other ELF targets probably want this as well, but on BSDs binutils is usually old so it doesn't matter.

utility. This is a particularly nice win because it removes a pile of
parameters from these routines. Also name them a bit better. I'm trying
to follow the pattern of 'emit' routines writing directly to what is
expected to be the final output, while 'print' routines take a output
stream argument and can be used to build up intermediate buffers, etc.

Also, fix a bug I spotted by inspection from my last commit where
'LastLoc' and 'LastNonNoteLoc' were reversed. It's really scary that
this didn't trigger a single test failure. Will be working on tests for
more of this functionality now.

across emissions.

1) The include stack printing is conditioned on non-note diagnostics,
   not just on warning diagnostics.
2) Those should be full source locations as they're tied to a source
   manager.
3) We should pass in the prior state to the TextDiagnostic constructor,
   allow it to mutate as diagnostics are emitted, and then cache the
   final state before tearing it down.

Some of this remains incomplete, specifically #3 isn't finished for the
non-note location. That'll come when the include stack printing sinks
down a level.

This also highlights how *completely* bug-ridden this code is. For
example, we currently do all these comparisons of a FullSourceLoc and
a SourceLocation... which silently does a SourceLocation to
SourceLocation comparison, completely disregarding the source manager
from whence one of the arguments came. Oops! Good thing in practice this
wasn't important, but it could in theory be suppressing caret
diagnostics in a second TU on a single clang invocation. I'm hoping to
hammer these bugs out as the refactorings occur, although for so many of
them it's really unlikely I can dream up a test case that would show the
potentially buggy behavior.
