This patch de-pessimizes the calculation of loop trip counts in
ScalarEvolution in the presence of multiple exits. Previously all
loops exits had to have identical counts for a loop trip count to be
considered computable. This pessimization was implemented by calling
getBackedgeTakenCount(L) rather than getExitCount(L, ExitingBlock)
inside of ScalarEvolution::getSmallConstantTripCount() (see the FIXME
in the comments of that function). The pessimization was added to fix
a corner case involving undefined behavior (pr/16130). This patch more
precisely handles the undefined behavior case allowing the pessimization
to be removed.
ControlsExit replaces IsSubExpr to more precisely track the case where
undefined behavior is expected to occur. Because undefined behavior is
tracked more precisely we can remove MustExit from ExitLimit. MustExit
was used to track the case where the limit was computed potentially
assuming undefined behavior even if undefined behavior didn't necessarily
occur.

Don't use an unqualified 'abs' function call with a builtin type.
This is dangerous for numerous reasons. The primary risk here is with
floating point or double types where if the wrong header files are
included in a strange order this can implicitly convert to integers and
then call the C abs function on the integers. There is a secondary risk
that even impacts integers where if the namespace the code is written in
ever defines an abs overload for types within that namespace the global
abs will be hidden. The correct form is to call std::abs or write 'using
std::abs' for builtin types (and only the latter is correct in any
generic context).
I've also added the requisite header to be a bit more explicit here.

[PPC64] VSX indexed-form loads use wrong instruction format
The VSX instruction definitions for lxsdx, lxvd2x, lxvdsx, and lxvw4x
incorrectly use the XForm_1 instruction format, rather than the
XX1Form instruction format. This is likely a pasto when creating
these instructions, which were based on lvx and so forth. This patch
uses the correct format.
The existing reformatting test (test/MC/PowerPC/vsx.s) missed this
because the two formats differ only in that XX1Form has an extension
to the target register field in bit 31. The tests for these
instructions used a target register of 7, so the default of 0 in bit
31 for XForm_1 didn't expose a problem. For register numbers 32-63
this would be noticeable. I've changed the test to use higher
register numbers to verify my change is effective.

This currently applies to Atom Silvermont, KNL and SKX.
