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.
