Since these assumptions are coming from OpenMP it makes sense to mark
them as such in the generic IR encoding. Standardized assumptions will
be named

  omp_ASSUMPTION_NAME

and extensions will be named

  ompx_ASSUMPTION_NAME

which is the OpenMP 5.2 syntax for "extensions" of any kind.

This also matches what the OpenMP-Opt pass expects.

Summarized,

  #pragma omp [...] assume[s] no_parallelism

now generates the same IR assumption annotation as

  __attribute__((assume("omp_no_parallelism")))
