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.

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.

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.

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.
