ffe0c407be 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.

7c323a8936 Fix a crash in SROA. The FunctionPass::doInitialization method was never 
being called so that Context was never initialized.  I'm not sure if this
is the right fix but at least it keeps opt from crashing.

1669f312b5 r76102 added the MachineCodeEmitter::processDebugLoc call and called it from 
the X86 Emitter.  This patch extends that to the rest of the targets that can
write to a MachineCodeEmitter: ARM, Alpha, and PPC.

b56b3ca224 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.
