Teach an instcombine to not pull trunc instructions through PHI nodes when both the source and dest are illegal types, since it would cause the phi to grow (for example, we shouldn't transform test14b's phi to a phi on i320). This fixes an infinite loop on i686 bootstrap with phi slicing turned on, so turn it back on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86483 91177308-0d34-0410-b5e6-96231b3b80d8
