libBitcodeReader is required since LLVM subversion rev 172906

[Longyi Qi]

Developers,
LLVM community has made this change on Jan 19 in rev 172906. Now all
libTooling based tools also depend on the bitcode reader library.

I have updated OCLint to catch up with this change in a branch. But
before it's merged to master, if you are working on LLVM codebase newer
than 172906, you need to add this library in order to pass the build.

There is an extra 'bitreader' between 'asmparser' and 'mblazeasmparser'.

The modified code has been merged into master, so this is no longer an issue.
