[PATCH] D71146: [llvm][VFABI] Add more testing for LLVM internal mangling.

[Francesco Petrogalli via Phabricator via llvm-commits]

fpetrogalli created this revision.
fpetrogalli added a reviewer: andwar.
Herald added a project: LLVM.
Herald added a subscriber: llvm-commits.

The tests cover the internal mangling for:

1. Masked signatures.
2. Scalable signatures.
3. Masked scalable signatures with linear.
