[llvm-branch-commits] [llvm] RuntimeLibcalls: Stop using defset for default calls (PR #147651)

[Matt Arsenault via llvm-branch-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/147651

This is redundant with the IsDefault field, so avoid a really
long enclosing pair of braces. This will make it easier to gradually
remove calls from the default set.
