I moved bl <label> in unconditionnal branch (immediate section.
For crc32, other crc32 instructions were not in basic test, so I've just added in forwarding test... I did not found any dependence graph built in llvm-mca, so not easy to check forwarding between instructions:
- ``instr1 a, b, c``
- `instr2 d, a, e`

Where ``a`` should be forwarded to source operand 1 of ``instr2``. Do you confirm?
