Disable -fmerge-all-constants as default. Summary: "-fmerge-all-constants" is a non-conforming optimization and should not be the default. It is also causing miscompiles when building Linux Kernel (https://lkml.org/lkml/2018/3/20/872). Fixes PR18538.

CodeGen: correct materialize temporary aggregates in ARC mode Avoid an assertion when materializing a lifetime type aggregate temporary. When performing CodeGen for ObjC++, we could generate a lifetime-only aggregate temporary by using an initializer list (which is effectively an array). We would reach through the temporary expression, fishing out the inner expression. If this expression was a lifetime expression, we would attempt to emit this as a scalar. This would eventually result in an assertion as the emission would eventually assert that the expression being emitted has a scalar evaluation kind. Add a case to handle the aggregate expressions. Use the EmitAggExpr to emit the aggregate expression rather than the EmitScalarInit. Addresses PR21347. llvm-svn: 220590
