Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The
...
asm printer will print it as offset*4. e.g. bne cr0, $+8.
The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Take advantage of the recent improvements to the liveintervals set (tracking
...
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.

Make the ProgramName variable a std::string so we can eliminate the path
...
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.
