We shouldn't need to read in function bodies for new functions found
during inlining, but something is expecting them to still be read
in. We should fix that code to not depend on them being read in, but
in the mean time reading them in anyway is at least correct, albeit
less efficient in time and space.
Fixes#49536.
Updates #50552.
