This patch implements custom codegen for the vec_replace_elt and
vec_replace_unaligned builtins.
These builtins map to the @llvm.ppc.altivec.vinsw and @llvm.ppc.altivec.vinsd
intrinsics depending on the arguments. The main motivation for doing custom
codegen for these intrinsics is because there are float and double versions of
the builtin. Normally, the converting the float to an integer would be done via
fptoui in the IR. This is incorrect as fptoui truncates the value and we must
ensure the value is not truncated. Therefore, we provide custom codegen to utilize
bitcast instead as bitcasts do not truncate.

The load builtins in altivec.h do not have const in the signature
for the pointer parameter. This prevents using them for loading
from constant pointers. A notable case for such a use is Eigen.
This patch simply adds the missing const.

Power10 introduces new instructions for vector multiply, divide and modulus.
These instructions can be exploited by the builtin functions: vec_mul, vec_div,
and vec_mod, respectively.
This patch aims adds the function prototype, vec_mod, as vec_mul and vec_div
been previously implemented in altivec.h.
This patch also adds the following front end tests:
vec_mul for v2i64
vec_div for v4i32 and v2i64
vec_mod for v4i32 and v2i64

Previously, the vins*vlx instructions were incorrectly defined with i64 as the
second argument. This patches fixes this issue by correcting the second argument
of the vins*vlx instructions/intrinsics to be i32.
Differential Revision: https://reviews.llvm.org/D84277
The implementation of the xvtlsbb builtins/intrinsics were not correct as the
intrinsics previously used i1 as an argument type. This patch changes the i1
argument type used in these intrinsics to be i32 instead, as having the second
as an i1 can lead to issues in the backend.
Differential Revision: https://reviews.llvm.org/D84291
Previously, the vins* intrinsic was incorrectly defined to have its second and
third argument arguments as an i64. This patch fixes the second and third
argument of the vins* instruction and intrinsic to have i32s instead.
