Fix PR4748: don't fold gep(bitcast(x)) into bitcast(gep) when x
...
is itself a bitcast. Since we have gep(bitcast(bitcast(y))) in this
case, just wait for the two bitcasts to get zapped. This prevents
instcombine from confusing some aliasing stuff, and allows it to
directly eliminate the load in the testcase.

inline the trivial AddToWorkList/RemoveFromWorkList methods

into their callers. simplify ReplaceInstUsesWith. Make
EraseInstFromFunction only add operands to the worklist if
there aren't too many of them (this was a scalability win
for crazy programs that was only infrequently enforced).
Switch more code to using EraseInstFromFunction instead of
duplicating it inline. Change some fcmp/icmp optimizations
to modify fcmp/icmp in place instead of creating a new one
and deleting the old one just to change the predicate.

PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's type
...
inferencing. As far as I can tell, these are equivalent to the existing
MVT::fAny, iAny and vAny types, and having both of them makes it harder
to reason about and modify the type inferencing code.
The specific problem in PR4795 occurs when updating a vAny type to be fAny
or iAny, or vice versa. Both iAny and fAny include vector types -- they
intersect with the set of types represented by vAny. When merging them,
choose fAny/iAny to represent the intersection. This is not perfect, since
fAny/iAny also include scalar types, but it is good enough for TableGen's
type inferencing.
