Fix Bug 4278: X86-64 with -tailcallopt calling convention
...
out of sync with regular cc.
The only difference between the tail call cc and the normal
cc was that one parameter register - R9 - was reserved for
calling functions through a function pointer. After time the
tail call cc has gotten out of sync with the regular cc.
We can use R11 which is also caller saved but not used as
parameter register for potential function pointers and
remove the special tail call cc on x86-64.

Add an "are types equivalent" operation that ignores the types that a pointer
...
points to while analyzing all other fields.
Use FoldingSetNodeID to produce a good hash. This dramatically decreases run
times.
Emit thunks. This means that it can look at all functions regardless of what
the linkage is or if the address is taken, but unfortunately some small
functions can be even shorter than the thunk because our backend doesn't yet
realize it can just turn these into jumps. This means that this pass will
pessimize code on average.
