6712: Fix proc macro token mapping r=jonas-schievink a=jonas-schievink
Diagnostics inside proc macros are currently incorrectly placed at their original offset, but inside the containing file. This fixes that, by allowing the creation of `ExpansionInfo` from non-`macro_rules!` macro invocations.

6698: Attach macro expansion errors to the right file r=jonas-schievink a=jonas-schievink
Previously it attached them to the result of the macro expansion (or, if no result was produced, to the file containing the invocation). Always use the file containing the invocation.
This doesn't seem to have any observable difference, but seems better in theory.
