Refactor removing module elements (#2489)

This creates utility functions for removing module elements: removing
one element by name, and removing multiple elements using a predicate
function. And makes other parts of code use it. I think this is a
light-handed approach than calling `Module::updateMaps` after removing
only a part of module elements.

This also fixes a bug in the inlining pass: it didn't call
`Module::updateMaps` after removing functions. After this patch callers
don't need to additionally call it anyway.
