By storing possible test vectors instead of combinations of conditions, the restriction is dramatically relaxed. This introduces two options to `cc1`: * `-fmcdc-max-conditions=32767` * `-fmcdc-max-test-vectors=2147483646` This change makes coverage mapping, profraw, and profdata incompatible with Clang-18. - Bitmap semantics changed. It is incompatible with previous format. - `BitmapIdx` in `Decision` points to the end of the bitmap. - Bitmap is packed per function. - `llvm-cov` can understand `profdata` generated by `llvm-profdata-18`. RFC: https://discourse.llvm.org/t/rfc-coverage-new-algorithm-and-file-format-for-mc-dc/76798 -- Change(s) since llvmorg-19-init-14288-g7ead2d8c7e91 - Update compiler-rt/test/profile/ContinuousSyncMode/image-with-mcdc.c
