Tighten up checking of the validity of casts. (1) The IR parser would
happily accept things like "sext <2 x i32> to <999 x i64>". It would
also accept "sext <2 x i32> to i64", though the verifier would catch
that later. Fixed by having castIsValid check that vector lengths match
except when doing a bitcast. (2) When creating a cast instruction, check
that the cast is valid (this was already done when creating constexpr
casts). While there, replace getScalarSizeInBits (used to allow more
vector casts) with getPrimitiveSizeInBits in getCastOpcode and isCastable
since vector to vector casts are now handled explicitly by passing to the
element types; i.e. this bit should result in no functional change.

Teach getCastOpcode about element-by-element vector casts. For example, "trunc"
can be used to turn a <4 x i64> into a <4 x i32> but getCastOpcode would assert
if you passed these types to it. Note that this strictly extends the previous
functionality: if getCastOpcode previously accepted two vector types (i.e. didn't
assert) then it still will and returns the same opcode (BitCast). That's because
before it would only accept vectors with the same bitwidth, and the new code only
touches vectors with the same length. However if two vectors have both the same
bitwidth and the same length then their element types have the same bitwidth, so
the new logic will return BitCast as before.

Start trying to make InstCombine preserve more debug info. The idea here is to set the debug location on the IRBuilder, which will be then right location in most cases. This should magically give many transformations debug locations, and fixing places which are missing a debug location will usually just means changing the code creating it to use the IRBuilder.
As an example, the change to InstCombineCalls catches a common case where a call to a bitcast of a function is rewritten.
