*	Revert "Temporarily Revert "Add basic loop fusion pass.""	Eric Christopher	2019-04-17	1	-0/+31
\| \| \| \| \| \| \| \|	The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
*	Temporarily Revert "Add basic loop fusion pass."	Eric Christopher	2019-04-17	1	-31/+0
\| \| \| \| \| \| \| \|	As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546

	not generate selects of two constants unless they are selects of 0 and 1. e.g. define i32 @t1(i32 %c, i32 %x) nounwind { %t1 = icmp eq i32 %c, 0 %t2 = lshr i32 %x, 18 %t3 = select i1 %t1, i32 %t2, i32 %x ret i32 %t3 } was turned into define i32 @t2(i32 %c, i32 %x) nounwind { %t1 = icmp eq i32 %c, 0 %t2 = select i1 %t1, i32 18, i32 0 %t3 = lshr i32 %x, %t2 ret i32 %t3 } For most targets, that means materializing two constants and then a select. e.g. On x86-64 movl %esi, %eax shrl $18, %eax testl %edi, %edi cmovne %esi, %eax ret => xorl %eax, %eax testl %edi, %edi movl $18, %ecx cmovne %eax, %ecx movl %esi, %eax shrl %cl, %eax ret Also, the optimizer and codegen can reason about shl / and / add, etc. by a constant. This optimization will hinder optimizations using ComputeMaskedBits. llvm-svn: 68142
