The8472 b98629bfbc lazify backtrace formatting for delayed diagnostics
This defers backtrace formatting to the point where we
actually want to flush delayed diagnostics. If they are discarded
before that point then we can avoid invoking the backtrace formatting
machinery which will parse debug info and symbol tables.

for debuginfo=2 this leads to a 20% walltime reduction of the UI testsuite
