This allows streams that only use BLOCKINFO for debugging purposes to omit
the block entirely. As long as another stream is available with the correct

As part of this commit, BitstreamReader gets a move constructor and move
assignment operator, as well as a takeBlockInfo method.

(2) Rename llvm-cov test inputs so the string "llvm-cov" doesn't get
substituted by lit within the input filenames on the RUN line.
(3) XFAIL llvm-cov.test because it asserts:
include/llvm/ADT/SmallVector.h:140: reference llvm::SmallVectorTemplateCommon<llvm::GCOVBlock *, void>::operator[](unsigned int) [T = llvm::GCOVBlock *]: Assertion `begin() + idx < end()' failed.
