748f1ae70b Added "DOUT" macro. This is used as a replacement for the std::cerr 
stream. It centralizes the use of std::cerr so that static c'tor/d'tors
aren't scattered around all over the place. The way to use it is like this:

       DOUT << "This is a status line: " << Var << "\n";

If "-debug" is specified, it will print. Otherwise, it'll not print. If
NDEBUG is defined, the DOUT does nothing.

77422c102b In LLVM 2.0 we won't use the runtime libraries as llvm-gcc3 support will 
be dropped. This patch pertains to removing the runtime directory from LLVM.

8aac7dc0ee This is a general clean up of the PowerPC ABI. Address several problems and 
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.

bd95b9d4ae Stop using isTwoAddress, switching to operand constraints instead. 
Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).

4a2af4e374 Remove the isTwoAddress property from the CodeGenInstruction class. It should 
not be used for anything other than backwards compat constraint handling.

Add support for a new DisableEncoding property which contains a list of
registers that should not be encoded by the generated code emitter.  Convert
the codeemitter generator to use this, fixing some PPC JIT regressions.

6d5a509e34 Switch loads over to use memri as the operand instead of a reg/imm operand 
pair for cleanliness.  Add instructions for PPC32 preinc-stores with commented
out patterns.  More improvement is needed to enable the patterns, but we're
getting close.
