bugpoint simplified repro .bc
Noticed that clang-1205.0.22.9 crashes while compiling following snippet
(reduced repro from sleefsimdsp.c):
```
#include <arm_sve.h>
svint32_t vreinterpret_vi2_vf(svfloat32_t vf) {
return __builtin_sve_reinterpret_s32_f32(vf);
}
```
Crash also reproduces in trunk and using bugpoint can be reduced to (attached):
```
; ModuleID = 'bugpoint-reduced-simplified.bc'
source_filename = "bar.cpp"
target datalayout = "e-m:o-i64:64-i128:128-n32:64-S128"
target triple = "arm64-apple-macosx11.0.0"
define <vscale x 4 x i32> @_Z19vreinterpret_vi2_vfu13__SVFloat32_t(<vscale x 4
x float> %vf) #0 {
entry:
ret <vscale x 4 x i32> zeroinitializer
}
attributes #0 = { "target-features"="+neon,+sve,+zcm,+zcz" }
!llvm.ident = !{!0}
!0 = !{!"clang version 13.0.0 (https://github.com/llvm/llvm-project.git
29a50c5864ddab283c1ff38694fb5926ce37b39a)"}
```
