This PR relands [#122992](https://github.com/llvm/llvm-project/pull/122992). Some machines were failing to run the `reflect-error.ll` test due to the RUN lines ```llvm ; RUN: not %if spirv-tools %{ llc -O0 -mtriple=spirv64-unknown-unknown %s -o /dev/null 2>&1 -filetype=obj %} ; RUN: not %if spirv-tools %{ llc -O0 -mtriple=spirv32-unknown-unknown %s -o /dev/null 2>&1 -filetype=obj %} ``` which failed when `spirv-tools` was not present on the machine due to running the command `not` without any arguments. These RUN lines have been removed since they don't actually test anything new compared to the other two RUN lines due to the expected error during instruction selection. ```llvm ; RUN: not llc -verify-machineinstrs -O0 -mtriple=spirv64-unknown-unknown %s -o /dev/null 2>&1 | FileCheck %s ; RUN: not llc -verify-machineinstrs -O0 -mtriple=spirv32-unknown-unknown %s -o /dev/null 2>&1 | FileCheck %s ```
