It doesn't stop or reconfigure the build, though, so the user will see
a broken build that magically succeeds at the next attempt. It is
technically possible to halt the build with a helpful message, and
even to automatically restart the build using the new dependencies as
it we did when llvm-config was used by cmake for learning
dependencies. This is left on the TODO list.

specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

and short. Well, it's kinda short. Definitely nasty and brutish.

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Built on Darwin and verified no llvm-core "make check" regressions.

instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

llvm-mc's purpose yet and we'll want to switch to creating semantic sections
at some point.

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.

I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.

just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.

Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.
