A call to @llvm.trap can be expected to be cold (i.e. unlikely to be reached in a normal program execution). Outlining paths which unconditionally trap is an important memory saving. As the hot/cold splitting pass (imho) should not treat all noreturn calls as cold, explicitly mark @llvm.trap cold so that it can be outlined. Split out of https://reviews.llvm.org/D54244.

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.
