With the addition of the `willreturn` attribute, functions that may not return (e.g. due to an infinite loop) are well defined, if they are not marked as `willreturn`. This patch updates `wouldInstructionBeTriviallyDead` to not consider calls that may not return as dead. This patch still provides an escape hatch for intrinsics, which are still assumed as willreturn unconditionally. It will be removed once all intrinsics definitions have been reviewed and updated.

This directory contains test cases for individual source features of LLVM. It is designed to make sure that the major components of LLVM support all of the features of LLVM, for very small examples. Entire programs should not go here. Regression tests for individual bug fixes should go into the test/Regression dir.
