f2976f16ce Fix this function to not say that longs have 8-byte alignment on X86/PPC. 
This method is really a gross hack, but at least we can make it work on
the targets we support right now.

This bug fix stops a crash in a testcase reduced from 176.gcc

c4abcbefb1 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

types and can have arbitrary 32- and 64-bit integer types indexing into
