This patch is the first part of https://llvm.org/OpenProjects.html#llvm_patch_coverage.

We have first define a new variable LLVM_TEST_COVERAGE which when set, pass --emit-coverage option to 
llvm-lit which will help in setting a unique value to LLVM_PROFILE_FILE for each RUN. So for example
coverage data for test case llvm/test/Analysis/AliasSet/memtransfer.ll will be emitted as 
build/test/Analysis/AliasSet/memtransfer.profraw
