- Clean up the code generated by tablegen:
* AddToISelQueue now takes one argument.
* ComplexPattern matching condition can now be shared.
* Eliminate passing unnecessary arguments to emit routines.
* Eliminate some unneeded SDOperand declarations in select routines.
* Other minor clean ups.
- This reduces foot print slightly: X86ISelDAGToDAG.o is reduced from 971k
to 823k.

paves the way for future changes, increases coallescing opportunities (in
theory, not witnessed in practice), and eliminates the really expensive
LiveIntervals::overlapsAliases method.

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.

Make the Win32 code exception free (untested/uncompiled) which forced some
interface changes which had ripple effect. This should be the last of 797.

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:

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.

Adjust implementation to match the new interface after exception handling
was removed in the Unix verison. NOTE: this hasn't been compiled yet!
llvm-svn: 29858
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.
