Don't enforce (normal) emission for pragma(inline, true) function templates, and don't cull lambdas (#3570)

Browse source 
With the new available_externally emission into each referencing CU, the
enforced regular emission from the module members tree shouldn't be
required anymore.

After adapting the codegen/inlining_templates.d lit-test accordingly (no
IR definitions anymore in .ll file, because available_externally doesn't
make it there), I've noticed that a lambda in imported and inlined
call_enforce_with_default_template_params() wasn't emitted - it got
culled by alreadyOrWillBeDefined().
Function/delegate literals aren't culled anymore.
