relax the assertion in SSPTR() and SSPTRt()
I added assertions in SSPTR() and SSPTRt() to try to ensure the new
SSize_t result from SSNEW*() wouldn't be truncated, but this
was too strict, requiring that the size matched exactly.
Relax this to allow the input offset to be the same or larger than
SSize_t.
Fixes #20504.
