  [OpenMP][NFCI] Split assertion message from assertion expression

We ended up with `llvm.assume(icmp ne ptr as(4) null, as(4) @str)`
because the string in address space 4 was not known to be non-null.
There is no need to create these assumes.

  [OpenMP][NFCI] Avoid storing non-constant values in ICV

If we store a constant in an ICV it is easier for the optimizer to
propagate it. Since we often use the full block for the thread limit and
the parallel team size, we can instead replace that dynamic value with a
constant that otherwise cannot occur, here 0.
