Switch lli back to using allocate-gvs-with-code behavior.

- Otherwise we get two regressions in llvm-test for applications which run out

Untangle a snarl that I discovered when updating the mangler,
...
starting in getCurrentFunctionEHName. Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin. This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.
This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.
