b7aa26303b ProfileData: Add support for the indexed instrprof format 
This adds support for an indexed instrumentation based profiling
format, which is just a small header and an on disk hash table.  This
format will be used by clang's -fprofile-instr-use= for PGO.

b9bd7f85a7 ProfileData: Introduce InstrProfWriter using the naive text format 
This isn't a format we'll want to write out in practice, but moving it
to the writer library simplifies llvm-profdata and isolates it from
further changes to the format.

This also allows us to update the tests to not rely on the text output
format.
