  -----------
  [MC/DC][Coverage] Introduce "Bitmap Bias" for continuous mode (#96126)

`counter_bias` is incompatible to Bitmap. The distance between Counters
and Bitmap is different between on-memory sections and profraw image.

Reference to `__llvm_profile_bitmap_bias` is generated only if
`-fcoverge-mcdc` `-runtime-counter-relocation` are specified. The
current implementation rejected their options.

```
Runtime counter relocation is presently not supported for MC/DC bitmaps
