gather bbs and conditions in a single walk through dominators
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.
