fix some type confusion in ReadVBR64: "Piece" should be only 32 bits,
...
not 64, because we read at most 32 bits at a time. OTOH, "Result" must
be 64-bits and insertion into it must be 64-bit clean. Thanks to Ivan
Sorokin for bringing this up.

Add two new record types to the blockinfo block:
...
BLOCKNAME and SETRECORDNAME. This allows a bitcode
file to be self describing with pretty names for
records and blocks in addition to numbers. This
enhances llvm-bcanalyzer to use this to print prettily.

Implement support for globally associating abbrevs with block IDs, which

relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.
