In TS 18661-1, getpayload had an unspecified return value for a non-NaN argument, while C2x requires the return value -1 in that case. This patch implements the return value of -1. I don't think this is worth having a new symbol version that's an alias of the old one, although occasionally we do that in such cases where the new function semantics are a refinement of the old ones (to avoid programs relying on the new semantics running on older glibc versions but not behaving as intended). Tested for x86_64 and x86; also ran math/ tests for aarch64 and powerpc.
