91f098c9f7 Add external definitions for commonly-used template specializations and add 
anchor methods to others.  This eliminates the vtable/template method bloat
in .o files that defining a cl::opt used to impose (~4K per .o file for one
cp::opt<unsigned>).

a72e220a25 New place to put compiler-specific functionality. This replaces Visibility.h, 
and provides macros that can be used to make explicit instantiations of
template specializations, which is a gcc-specific feature.

6e08e7035f Eliminate SelectNodeTo() and getTargetNode() variants which take more than 
3 SDOperand operands. They are replaced by versions which take an array
of SDOperand and the number of operands.

3c5fa40194 Fix target matching weights, so that ppc-darwin modules are codegen with the 
ppc target, not the itanium target, when run on an itanium machine.
This should fix the CodeGen/PowerPC regtest failures on itanium.

b96b719724 - Clean up tablegen dag isel generator code. 
- 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.

ec9c7fa089 Completely change the way that joining with physregs is implemented. This 
paves the way for future changes, increases coallescing opportunities (in
theory, not witnessed in practice), and eliminates the really expensive
LiveIntervals::overlapsAliases method.

ccbb645459 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.

e2b7b29a82 For PR797: 
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:

28645a15bd 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.
