Jingyue Wu f6eb7e3175 Canonicalize addrspacecast ConstExpr between different pointer types ... As a follow-up to r210375 which canonicalizes addrspacecast instructions, this patch canonicalizes addrspacecast constant expressions. Given clang uses ConstantExpr::getAddrSpaceCast to emit addrspacecast cosntant expressions, this patch is also a step towards having the frontend emit canonicalized addrspacecasts. Piggyback a minor refactor in InstCombineCasts.cpp Update three affected tests in addrspacecast-alias.ll, access-non-generic.ll and constant-fold-gep.ll and added one new test in constant-fold-address-space-pointer.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211004 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-15 21:40:57 +00:00
