[PATCH] Make Driver::link and LinkingContext::validate return true on success.

[Rui Ueyama]

This patch inverts the return value of these functions, so that they return
"true" on success and "false" on failure. The meaning of boolean return value
was mixed LLD; for example, InputGraph::validate() return true on success.
With this patch they'll become consistent.
