It initially found some false positives due to unusual constructs in a minority of tests; all such cases were disambiguated first in commit r186621. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186624 91177308-0d34-0410-b5e6-96231b3b80d8

* When promoting integer vectors we often create ext-loads. This patch adds aNadav Rotem2011-09-18
dag-combine optimization to implement the ext-load efficiently (using shuffles). For example the type <4 x i8> is stored in memory as i32, but it needs to find its way into a <4 x i32> register. Previously we scalarized the memory access, now we use shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139995 91177308-0d34-0410-b5e6-96231b3b80d8
