Don't use consecutive numbers for basic blocks from different functions.

Consecutive numbers can make it difficult to combine assembly output from
different compiler runs, which is done by the check/checkfile scripts to find
bugs in the SPEC suite.  If the number of basic blocks of a function changed
between compiler runs, the assembler will likely complain about duplicate labels.
Leaving a bit more space, e.g. 100, is a pragmatic fix.
