Original commit message: S390:Update inline asm constraint in test-platform The GetStackPointer() routine in test-platform uses an inline assembly code to store the current stack pointer value into a static variable sp_addr. The existing asm code for S390 uses an ST/STG instruction, with the memory operand associated with the general ('=g') constraint to sp_addr. On GCC 4.8.5, the GCC compiler got confused and treated sp_addr as an integer operand instead of memory operand, resulting in a store being emitted that writes to an invalid meory location. Given the specific store instructions being inlined here, we should restict the sp_addr operand to explicitly be a memory operand using '=m' instead of '=g'.
