Subject: [LV] Make the new getter return a const reference. NFC
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2978728dd25804cf2202b143d94a2d645627c09d;p=llvm

[LV] Make the new getter return a const reference. NFC

LoopVectorizationLegality holds a constant reference to LAI, so this
will have to be const as well.

Also added missed function comment.
