Fixed.  With these changes, LLVM-tblgen __STARTS TO WORK__.  Building the X86
backend, it builds all of:
X86GenInstrInfo.inc   X86GenRegisterInfo.h.inc  X86GenRegisterNames.inc
X86GenInstrNames.inc  X86GenRegisterInfo.inc

... with the LLVM compiled tablegen, finally crashing when trying to generate
the instruction selector.  It also crashes when trying to create the sparc
instruction emitter.  Still, this is _HUGE_ progress: tblgen uses a lot of
non-trivial C++ stuff, including the command line option parser, hunks of the
STL, etc.

Here are the main LLVM patches:

Here's the GCC front-end patch, to link to -lcrtend instead of crtend.o
