* Removed gtest_main.cc: we have our own main() elsewhere * Simplified the Makefile as we don't need SOURCES * Moved the internal header to gtest/internal/ * Simplified the Makefile to remove -I param to CPP.Flags * Updated README.LLVM with all the steps I took to massage GTest to work in LLVM so far git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61540 91177308-0d34-0410-b5e6-96231b3b80d8
