Remove exception handling from the bytecode archiver and adjust the llvm-ar
tool to accommodate the new interfaces.

instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:
1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
better solution.
3. Implements PR865, "coallescing" away the second copy in code like:
A = B
...
B = A
This also includes changes to symbolically print registers in intervals
when possible.

Demote check for bison from error to warning and make sure that the
makefile can handle an empty definition for BISON variable.

Adjust implementation to match the new interface after exception handling
was removed in the Unix verison. NOTE: this hasn't been compiled yet!

bytes in the outstring function.

Final remove of exception handling from this file. lib/System can no longer
throw exceptions so there's no need for try/catch blocks here.

portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages. Instead of:
/path/to/llvm/bin/directory/toolname: error message
we will now get:
toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

Remove exceptions from the Path::create*OnDisk methods. Update their users
to handle error messages via arguments and result codes.

memory pressure. This order spaces out large executables with small ones in
between so that in a -j2 or -j3 build, it only attempts to build only one
large executable at time. If you're doing -j4, you probably have enuogh
memory anyway.

version to be left blank if the build failed.
Also corrected a problem where if the build failed the nightly tester
would still try to read the results of the Dejagnutests log even
though it didnt exist.

Adjust the use of MappedFile to its new non-throwing interface. We just
propagate the exceptions if an error occurs. This will get cleaned up
later, incrementally.

Make the Bytecode Reader use setjmp/longjump instead of exceptions to handle
errors. The alternative was even uglier than setjmp/longjump as it would
impact the interface and workings of nearly every function in the reader.
