  [llvm-extract] support unnamed bbs. (#135140)

Dear developer:

I have recently working with LLVM IR and I want to isolate basic blocks
using the command "llvm-extract". However, I found that the command
option "llvm-extract --bb func_name:bb_name" will only function when
dumping source code into IRs with options "-fno-discard-value-names".
That is to say, the "llvm-extract" command cannot support unnamed basic
blocks, which is a default output of the compiler. So, I made these
changes and hope they will make LLVM better.

Best regards,
