All but 2 of the vector builtins are only used by clang_builtin_alias. When using clang_builtin_alias, the type string of the builtin is never checked. Only the types in the function definition used for the alias are checked. This patch takes advantage of this to share a single builtin for many different types. We already used type overloads on the IR intrinsic so the codegen for the builtins that are being merge were already the same. This extends the type overloading to the builtins. I had to make a few tweaks to make this work. -Floating point vector-vector vmerge now uses the vmerge intrinsic instead of the vfmerge intrinsic. New isel patterns and tests are added to support this. -The SemaChecking for the immediate of vset_v/vget_v has been removed. Determining the valid range is harder now. I've added masking to ManualCodegen to ensure valid IR for invalid input. This reduces the number of builtins from ~25000 to ~1100.
