llvm::cl::opt flags are compiled out in non-asserts builds, making these
debug flags unavailable in an important category of use cases — debugging
a release compiler in lldb. By promoting them to Swift frontend flags stored
in DiagnosticOptions/SILOptions, they are available in all build
configurations.
The three existing flags are migrated:
-diagnostics-assert-on-error
-diagnostics-assert-on-warning
-sil-region-isolation-assert-on-unknown-pattern
(backing field renamed to AbortOnUnknownRegionIsolationPatternError)
A new flag is added:
-diagnostics-assert-on-group <group>
Traps when any diagnostic belonging to the named group is emitted,
allowing targeted breakpoints on a single diagnostic group rather than
all errors or all warnings.
The assert-on-{error,warning,group} flags are intentionally kept separate
from the normal diagnostic suppression/escalation machinery so that they
remain useful while other diagnostics are also being emitted.
Tests are added for all four flags.
