DS instructions that access local memory can only uses addresses that
are less than or equal to the value of M0. When M0 is uninitialized,
then we experience undefined behavior.
This patch also changes the behavior to emit S_WQM_B64 on pixel shaders
no matter what kind of DS instruction is used.

| How to organize the lit tests |
+==============================================================================+
- If you write a test for matching a single DAG opcode or intrinsic, it should
go in a file called {opcode_name,intrinsic_name}.ll (e.g. fadd.ll)
- If you write a test that matches several DAG opcodes and checks for a single
ISA instruction, then that test should go in a file called {ISA_name}.ll (e.g.
bfi_int.ll
- For all other tests, use your best judgement for organizing tests and naming
the files.
+==============================================================================+
| Naming conventions |
+==============================================================================+
- Use dash '-' and not underscore '_' to separate words in file names, unless
the file is named after a DAG opcode or ISA instruction that has an
underscore '_' in its name.
