Allow multiclass def names to contain "#NAME"" where TableGen replaces
...
#NAME# with the name of the defm instantiating the multiclass. This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA. For example:
multiclass SSE_AVX_Inst<...> {
def SS : Instr<...>;
def SD : Instr<...>;
def PS : Instr<...>;
def PD : Instr<...>;
def V#NAME#SS : Instr<...>;
def V#NAME#SD : Instr<...>;
def V#NAME#PS : Instr<...>;
def V#NAME#PD : Instr<...>;
}
defm ADD : SSE_AVX_Inst<...>;

ThreadEdge directly. This shares the code, but is just a refactoring.

loops (goodness) but also prevents it from threading in other cases that
are beneficial (see the comment above FindFunctionBackedges).
