gcov expects every function to contain an entry block that unconditionally branches into the next block. clang does not implement basic blocks in this manner, so gcov did not output correct branch info if the entry block branched to multiple blocks. This change splits every function's entry block into an empty block and a block with the rest of the instructions. The instrumentation code will take care of the rest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195513 91177308-0d34-0410-b5e6-96231b3b80d8
