cmd/link: put padding between functions, not at the end of a function

Functions should be declared to end after the last real instruction, not
after the last padding byte. We achieve this by adding the padding while
assembling the text section in the linker instead of adding the padding
to the function symbol in the compiler. This change makes dtrace happy.

TODO: check that this works with external linking

Fixes #15969
