Add tests for coverage mapping generation. This patch adds the tests for the coverage mapping generation. Most of the tests check the mapping regions produced by the generator, and one checks the llvm IR. Differential Revision: http://reviews.llvm.org/D4847 llvm-svn: 215995

// Check the data structures emitted by coverage mapping
[PGO] cc1 option name change for profile instrumentation This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level. Review: http://reviews.llvm.org/D16730 llvm-svn: 259811
