Commit ed6fd2aed58f2cca99f15331bf68999c0e6df370, "PR middle-end/95126: Expand
small const structs as immediate constants.", introduces an ICE for the
attached test case (from glibc) on mips64-linux-gnu. Compile with: -mabi=n32
-O2

Hi Joseph. Sorry again for the breakage. Hopefully, the
load_register_parameters ICE is now resolved.  Can you confirm that glibc now
builds without problems on MIPS?
