bors 0df1ddc185 Auto merge of #99556 - davidtwco:collapse-debuginfo, r=wesleywiser 
ssa: implement `#[collapse_debuginfo]`

cc #39153 rust-lang/compiler-team#386

Debuginfo line information for macro invocations are collapsed by default - line information are replaced by the line of the outermost expansion site. Using `-Zdebug-macros` disables this behaviour.

When the `collapse_debuginfo` feature is enabled, the default behaviour is reversed so that debuginfo is not collapsed by default. In addition, the `#[collapse_debuginfo]` attribute is available and can be applied to macro definitions which will then have their line information collapsed.
