Git commit 119a0fb1642c3d294d055bbe62163ed1e9464541 by Matt Arsenault on 22/07/2026 at 11:09..
PowerPC: Rename "float-abi" module flag to "long-double-type"

PPC was emitting a "float-abi" module flag for indicating the type of long
double. The "float ABI" naming is already widely taken by soft vs. hard
float controls (e.g., the clang flag is called -mfloat-abi), so this shouldn't
have taken it. This should also not be PPC specific; x86 has the same problem.
Rename the flag to the more specific long-double-type, and add appropriate
verification and documentation (which was also missing). Also changes the value
names to match the IR type names.
