[MC] Allow Stackmap sections after DWARF in MachO.
Summary:
Mixing stackmaps and DWARF in a single file triggers an assertion in
MCMachOStreamer as stackmap sections are emitted in AsmPrinter::emitEndOfAsmFile
after the DWARF sections have already been emitted.
Since it should be safe to emit stackmap sections after DWARF sections this
patch relaxes the assertion to allow that.
