long and cumbersome.
The base class for ranges is currently value_range_base, which is
rather long and cumbersome. It also occurs more often than the derived
class of value_range. To avoid confusion, and save typing, this
patch does a global rename from value_range to value_range_equiv,
and from value_range_base to value_range.
This way, the base class is simply value_range, and the derived
class is value_range_equiv which explicitly states what it does.

This patch makes value_range_base::set convert POLY_INT_CST bounds
into the worst-case INTEGER_CST bounds. The main case in which this
gives useful ranges is a lower bound of A + B * X becoming A when B >= 0.
E.g.:
[32 + 16X, 100] -> [32, 100]
[32 + 16X, 32 + 16X] -> [32, MAX]
But the same thing can be useful for the upper bound with negative
X coefficients.

This patch allows users of the substitute_and_fold_engine to
enable folding all statements. It is now enabled for VRP which
is needed for the match.pd pattern in patch 2/2.
The loop versioning pass was missing one case when
deconstructing addresses that would only be triggered after
this patch for me:
It could handle addition and subsequent convert/nop but not
a convert/nop directly. This would cause the hash to be
calculated differently and, in turn, cause the pass to miss
a versioning opportunity. Fixed this by adding the missing
case.
