[LV] Delete unneeded scalar GEP creation code
The code for generating scalar base pointers in vectorizeMemoryInstruction is
not needed. We currently scalarize all GEPs and maintain the scalarized values
in VectorLoopValueMap. The GEP cloning in this unneeded code is the same as
that in scalarizeInstruction. The test cases that changed as a result of this
patch changed because we were able to reuse the scalarized GEP that we
previously generated instead of cloning a new one.

[IR] Use a binary search in DataLayout::getAlignmentInfo
Summary:
We currently do a linear scan through all of the Alignments array entries anytime getAlignmentInfo is called. I noticed while profiling compile time on a -O2 opt run that this function can be called quite frequently and was showing about as about 1% of the time in callgrind.
This patch puts the Alignments array into a sorted order by type and then by bitwidth. We can then do a binary search. And use the sorted nature to handle the special cases for INTEGER_ALIGN. Some of this is modeled after the sorting/searching we do for pointers already.
This reduced the time spent in this routine by about 2/3 in the one compilation I was looking at.
We could maybe improve this more by using a DenseMap to cache the results, but just sorting was easy and didn't require extra data structure. And I think it made the integer handling simpler.

This removes the 'remapTypeIndices' method on every TypeRecord class. My
original idea was that this would be the beginning of some kind of

of a TypeRecord, so that we could write generic graph algorithms for
them without duplicating the knowledge of which fields are type index
fields everywhere. This never happened, and nothing else uses this
method. I need to change the API to deal with merging into IPI streams,

Make the home_directory test a little more resilient.
It's possible (albeit strange) for $HOME to intentionally
point somewhere other than the user's home directory as
reported by the password database. Our test shouldn't fail

from the password database before unsetting $HOME, rather
than comparing the return value of home_directory() to the

[ScalarEvolution] Predicate implication from operations
This patch allows SCEV predicate analysis to prove implication of some expression predicates
from context predicates related to arguments of those expressions.
It introduces three new rules:
For addition:
(A >X && B >= 0) || (B >= 0 && A > X) ===> (A + B) > X.
For division:
(A > X) && (0 < B <= X + 1) ===> (A / B > 0).
(A > X) && (-B <= X < 0) ===> (A / B >= 0).
Using these rules, SCEV is able to prove facts like "if X > 1 then X / 2 > 0".
They can also be combined with the same context, to prove more complex expressions like
"if X > 1 then X/2 + 1 > 1".

[Hexagon] Recognize polynomial-modulo loop idiom again
Regain the ability to recognize loops calculating polynomial modulo
operation. This ability has been lost due to some changes in the
preceding optimizations. Add code to preprocess the IR to a form
that the pattern matching code can recognize.

Rename AttributeSet to AttributeList
Summary:
This class is a list of AttributeSetNodes corresponding the function
prototype of a call or function declaration. This class used to be
called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is
typically accessed by parameter and return value index, so
"AttributeList" seems like a more intuitive name.
Rename AttributeSetImpl to AttributeListImpl to follow suit.
It's useful to rename this class so that we can rename AttributeSetNode
to AttributeSet later. AttributeSet is the set of attributes that apply
to a single function, argument, or return value.
