*** TEST RESULTS FOR COMMIT d12307c199dfdb9cad1ea79d2626224e705089a3 ***

Author: Pierre-Marie de Rodat <derodat@adacore.com>
Branch: master
Commit: d12307c199dfdb9cad1ea79d2626224e705089a3

Replace the block_found global with explicit data-flow
As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found.  This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.
