Several tests for the new fake use intrinsic are failing on NVPTX
buildbots due to relying on behaviour for their expected triple;
this commit adds that triple to each of them to prevent failures.
Fixes commit 3d08ade (#86149).
Example buildbot failures:
https://lab.llvm.org/buildbot/#/builders/160/builds/4175
https://lab.llvm.org/buildbot/#/builders/180/builds/4173
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
