Adam Nemet 06ccf0145f [LVer] Remove unused Pass parameter from versionLoop, NFC

Adam Nemet dfaeb33ec7 [LoopVer] Optionally allow using memchecks from LAA
r243382 changed the behavior to always require a set of memchecks to be
passed to LoopVer.  This change restores the prior behavior as an
alternative to the new behavior.  This allows the checks to be
implicitly taken from the LAA object.

Patch by Ashutosh Nema!

Adam Nemet 6b6082dc42 [LoopVer] Remove unused needsRuntimeChecks(), NFC
The previous commits moved this functionality into the client.

Also remove the now unused member variable.

Adam Nemet 252d529b6c [LoopVer] Add missing std::move
The reason I was passing this vector by value in the constructor so that
I wouldn't have to copy when initializing the corresponding member but
then I forgot the std::move.

The use-case is LoopDistribution which filters the checks then
std::moves it to LoopVersioning's constructor.  With this interface we
can avoid any copies.

Adam Nemet 0a674401bf [LDist][LVer] Explicitly pass the set of memchecks to LoopVersioning, NFC
Before the patch, the checks were generated internally in
addRuntimeCheck.  Now, we use the new overloaded version of
addRuntimeCheck that takes the ready-made set of checks as a parameter.

The checks are now generated by the client (LoopDistribution) with the
new RuntimePointerChecking::generateChecks API.

Also the new printChecks API is used to print out the checks for
debugging.

This is to continue the transition over to the new model whereby clients
will get the full set of checks from LAA, filter it and then pass it to
LoopVersioning and in turn to addRuntimeCheck.

Adam Nemet 7cdebac0c8 [LAA] Lift RuntimePointerCheck out of LoopAccessInfo, NFC
I am planning to add more nested classes inside RuntimePointerCheck so
all these triple-nesting would be hard to follow.

Also rename it to RuntimePointerChecking (i.e. append 'ing').

Adam Nemet 215746b45a [LoopDist/LoopVer] Move LoopVersioning to a new module, NFC
Summary:
The class will obviously need improvement down the road.  For one, there
is no reason that addPHINodes would have to be exposed like that.  I
will make this and other improvements in follow-up patches.

The main goal is to be able to share this functionality.  The
LoopLoadElimination pass I am working on needs it too.  Later we can
move other clients as well (LV and Ashutosh's LICMVer).
