the relationship with MergeFunctions.cpp's isEquivalentOperation,
and make a trivial code reordering so that the two functions are
easier to compare.

Fix the name of Instruction::isSameOperationAs in MergeFunction.cpp's
isEquivalentOperation's comment, and fix a nearby 80-column violation.

argument deduction failed. For example, given

  template<typename T> struct is_same<T, T> { ... };

template argument deduction will fail for is_same<int, float>, and now
reports enough information

Right now, we don't do anything with this extra information, but it
can be used for informative diagnostics that say, e.g., "template
argument deduction failed because T was deduced to 'int' in one
context and 'float' in another".

It's an error to use a function declared in a class definition as a default argument before the function has been declared.

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.

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.
