Peter Collingbourne	e8516587a2	Bitcode: Change reader interface to take memory buffers. ... As proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106595.html This change also fixes an API oddity where BitstreamCursor::Read() would return zero for the first read past the end of the bitstream, but would report_fatal_error for subsequent reads. Now we always report_fatal_error for all reads past the end. Updated clients to check for the end of the bitstream before reading from it. I also needed to add padding to the invalid bitcode tests in test/Bitcode/. This is because the streaming interface was not checking that the file size is a multiple of 4.
