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.

lib/Support/CommandLine.cpp:
Many changes suggested by Chris. It's okay, I'll recover from the emotional

Collapse ParseCStringVector into ParseStringVector.  Comment it.
Make it take a const input.

addPassesToJITCompile and addPassesToEmitMachineCode now take a
 FunctionPassManager, to support function-at-a-time compilation and
 emission of code.

Deconstify parameter to getPointerToFunction().
Use a FunctionPassManager instead of a PassManager.

Deconstify parameter to getPointerToFunction().
Run passes on single function (hey, just-in-time compilation!)
 instead of the entire module that contains it.

In ExecutionEngine::getPointerToGlobal(), throw away const qualifier

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.

Reorganize tests because we no longer cannonicalize X != 0 -> cast X to bool
In fact, we plan to eliminate cast to bool entirely.
