Fix for llvm-dis/llvm-bcanalyzer overflows
Summary:
These tools failed for a very large bitcode file produced by LTO due to
64-bit values being assigned to 32-bit types. For the BitstreamReader.h
fix, the value initially fit into the 32-bit unsigned, but there was an
overflow when multiplying by 32 furter below to compute the bit offset.
No test case in the patch as this requires a huge bitcode file.
