Duncan P. N. Exon Smith 5702287809 CodeGen: Update DFAPacketizer API to take MachineInstr&, NFC
In all but one case, change the DFAPacketizer API to take MachineInstr&
instead of MachineInstr*.  In DFAPacketizer::endPacket(), take
MachineBasicBlock::iterator.  Besides cleaning up the API, this is in
search of PR26753.

Duncan P. N. Exon Smith 6307eb5518 CodeGen: TII: Take MachineInstr& in predicate API, NFC
Change TargetInstrInfo API to take `MachineInstr&` instead of
`MachineInstr*` in the functions related to predicated instructions
(I'll try to come back later and get some of the rest).  All of these
functions require non-null parameters already, so references are more
clear.  As a bonus, this happens to factor away a host of implicit
iterator => pointer conversions.

No functionality change intended.

Duncan P. N. Exon Smith d84f600653 CodeGen: Bring back MachineBasicBlock::iterator::getInstrIterator()...
This is a little embarrassing.

When I reverted r261504 (getIterator() => getInstrIterator()) in
r261567, I did a `git grep` to see if there were new calls to
`getInstrIterator()` that I needed to migrate.  There were 10-20 hits,
and I blindly did a `sed ...` before calling `ninja check`.

However, these were `MachineInstrBundleIterator::getInstrIterator()`,
which predated r261567.  Perhaps coincidentally, these had an identical
name and return type.

This commit undoes my careless sed and restores
`MachineBasicBlock::iterator::getInstrIterator()`.

Duncan P. N. Exon Smith c5b668deb8 Revert "CodeGen: MachineInstr::getIterator() => getInstrIterator(), NFC"
This reverts commit r261504, since it's not obvious the new name is
better:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20160222/334298.html

I'll recommit if we get consensus that it's the right direction.

Krzysztof Parzyszek dac7102874 [Packetizer] Add AliasAnalysis as a parameter to the packetizer
This will make the depedence graph more accurate if an alias analysis
is provided. If nullptr is specified in its place, the behavior will
remain as it is currently.

Matthias Braun 93563e7032 ScheduleDAGInstrs: Remove IsPostRA flag; NFC
ScheduleDAGInstrs doesn't behave differently before or after register
allocation. It was only used in a method of MachineSchedulerBase which
behaved differently in MachineScheduler/PostMachineScheduler. Change
this to let MachineScheduler/PostMachineScheduler just pass in a
parameter to that function.

The order of the LiveIntervals* and bool RemoveKillFlags paramters have
been switched to make out-of-tree code fail instead of unintentionally
passing a value intended for the IsPostRA flag to the (previously
following and default initialized) RemoveKillFlags.

Duncan P. N. Exon Smith a73371a9b7 AMDGPU: Remove implicit ilist iterator conversions, NFC
One of the changes in lib/Target/AMDGPU/AMDGPUMCInstLower.cpp was a new
one.  Previously, bundle iterators and single-instruction iterators
could be compared to each other (comparing on underlying pointers).
I changed a comparison from using `MBB->end()` to using
`MBB->instr_end()`, since both end iterators should point at the some
place anyway.

I don't think the implicit conversion between the two iterator types is
a good idea since it's fairly easy to accidentally compare to the wrong
thing (they aren't always end iterators).  Otherwise I would have just
added the conversion.

Even with that, no there should be functionality change here.
