 - Particularly nice for small constant strings, which get optimized
   down nicely. On a synthetic benchmark writing out "hello" in a
   loop, this is about 2x faster with gcc and 3x faster with
   llvm-gcc. llc on insn-attrtab.bc from 403.gcc is about .5% faster.

 - I tried for a fancier solution which wouldn't increase code size as
   much (by trying to match constant arrays), but can't quite make it
   fly.

when creating symbolic values, we distinguish between location and non-location
values. For location values, we create a symbolic region instead of a
loc::SymbolVal.
