Chris Lattner 4b422520ca Fix ABI issue: Longs really do need to be only 4 byte aligned on X86.
This bug caused miscompilation of programs using 'struct stat', but only if
compiled with support for 64-bit filesystems.  This could in theory effect
other things, but only if the LLVM code shared data structures with native code.

Brian Gaeke 02cbe2824c addPassesToJITCompile now takes a FunctionPassManager, to support
function-at-a-time compilation and emission of code.
Separate addPassesToEmitAssembly from addPassesToJITCompile, because
 the latter requires you to use FunctionPasses, and the former might
 diverge anyway.

Chris Lattner e61db425e8 Add support for a pattern matching instruction selector. This is still in
the early implementation phases, so it is disabled by default

Brian Gaeke a92dce471b Printer.cpp: Ditch addRequired/getAnalysis, because they leave
Printer::doFinalization() out in the cold.  Now we pass in a TargetMachine
  to Printer's constructor and get the TargetData from the TargetMachine.
 Don't pass TargetMachine or MRegisterInfo objects around in the Printer.
 Constify TargetData references.
X86.h: Update comment and prototype of createX86CodePrinterPass().
X86TargetMachine.cpp: Update callers of createX86CodePrinterPass().

Brian Gaeke ac94bab876 lib/Target/X86/X86TargetMachine.{cpp,h}: Add initial version
(non-working) of llc guts for X86, and add a prototype for it.

Chris Lattner b2809dc6b5 Implement code to keep the stack pointer aligned to an 8 byte boundary.
This improves the performance of the power benchmark by a few percent.
This will be neccesary for SSE code, which requires 16 byte alignment of
the stack.
