Clean up the function to build scop's basic blocks and the function
that gathers the conditions under which a basic block is executed. We remove
one traversal of the dominator tree.
This refactoring was triggered by the need of a vec<bb> of all the basic blocks
in a region. We will use that vector in a patch that removes the out-of-ssa
translation of scalar dependences: we will iterate through the basic blocks of a
region to record scalar dependences crossing bbs or going out of the region.
The patch passes bootstrap and regtest on x86_64-linux.

This patch introduces the Package_alias class which is a
finer representation of the different between a package and the
aliases it is imported under. Each alias keeps track of the location
of its import statement and how many times that alias has been used.
This allows the gofrontend to report when a specific import has not
been used even if a symbol from the package has been used by another
import.
