ubsan: Avoid i386 UBSAN handler crashes with Clang
When generating Runtime Calls, Clang doesn't respect the -mregparm=3
option used on i386. Hopefully this will be fixed correctly in Clang 19:

but we need to fix this for earlier Clang versions today. Force the
calling convention to use non-register arguments.
