Handle more imm forms, and load small negative i32 constants without hitting memory (should do the same for arbitrary zero extended small negative constants)

the JIT memory manager will construct a GOT if you want it too.  Also, it places the constants in the allocated memory, rather than a malloc area

llvm-svn: 22497

allow constants to be relocated like GV (necessary for alpha, as constants are relocated with globals, not with .text), and allow targets to have a GOT managed for them

This is the first incremental patch to implement this feature. It adds no
functionality to LLVM but setup up the information needed from targets in
order to implement the optimization correctly. Each target needs to specify
the maximum number of store operations for conversion of the llvm.memset,
llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations.
The limit needs to be chosen at the threshold of performance for such an
optimization (generally smallish). The target also needs to specify whether
the target can support unaligned stores for multi-byte store operations.
This helps ensure the optimization doesn't generate code that will trap on
an alignment errors.
More patches to follow.
