Subject: [PATCH 1/2] [lldb] Fix progress reporting for
SymbolLocatorDebugSymbols
This fixes two issues related to the DebugSymbols symbol locator:
1. Only the default symbol locator plugin reports progress. On Darwin,
which uses the DebugSymbols framework we need to report the same
progress form the corresponding SymbolLocator plugin.
2. Forceful dSYM lookups, for example when using `add-dsym`, use a
different code path that currently does not report progress, which
is confusing. Here the progress event can be more specific and
specify its downloading a symbol file rather than just locating it
as we'll always shell out to dsymForUUID or its equivalent.
