Stop only if there aren't any usable algorithms
When searching for an usable algorithm with -minline-all-stringops,
decide_alg stops when it sees libcall even if there is a usable
algorithm. It goes into an infinite loop. This patch changes
decide_alg to stop searching only if there aren't any usable algorithms.
Testd on Linux/x86-64.
