4ba844388c [C++11] More 'nullptr' conversion. In some cases just using a boolean check instead of comparing to nullptr.

9f998de891 [C++11] Add 'override' keyword to virtual methods that override their base class.

46f6fe7a45 Remove VirtRegMap::getRegAllocPref().
Now that there can be multiple hint registers from targets, it doesn't
make sense to have a function that returns 'the' preferred register.

980bddfb1c Use MRI::getSimpleHint() instead of getRegAllocPref() in remaining cases.
Targets can provide multiple hints now, so getRegAllocPref() doesn't
make sense any longer because it only returns one preferred register.
Replace it with getSimpleHint() in the remaining heuristics. This
function only

fc6374439e Add VirtRegMap::hasKnownPreference().
Virtual registers with a known preferred register are prioritized by
RAGreedy. This function makes the condition explicit without depending
on getRegAllocPref().

255f89faee Sort the #include lines for the include/... tree with the script.
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

1ead68d769 Make the LiveRegMatrix analysis available to targets.
No functional change, just moved header files.

Targets can inject custom passes between register allocation and
rewriting. This makes it possible to tweak the register allocation
before rewriting, using the full global interference checking available
from LiveRegMatrix.
