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.

Replace isTrapping with a new, similar method called
isSafeToSpeculativelyExecute. The new method is a bit closer to what
the callers actually care about in that it rejects more things callers
don't want.  It also adds more precise handling for integer
division, and unifies code for analyzing the legality of a speculative
load.

Assume an inline asm might be a call, so we get
stack alignment right when it is.  This is not
ideal but conservatively correct.  Adjust a test
to compensate for changed stack offset value.
