testcase
This regression was introduced by r225061, [SROA] Teach SROA how to much more
intelligently handle split loads and stores.
Testcase:
target datalayout = "p:16:16-p21:32:16"
%rec221 = type { i16 addrspace(21)*, i32 }
define void @foo() {
%entry.80 = alloca %rec221
%1 = bitcast %rec221* %entry.80 to i64*
%2 = load i64 addrspace(21)* undef
store i64 %2, i64* %1
%entry.80.0._tmp337.sroa_idx = getelementptr inbounds %rec221* %entry.80, i16
0, i32 0
%entry.80.0._tmp338 = load i16 addrspace(21)** %entry.80.0._tmp337.sroa_idx
ret void
