Currently, the compiler crashes in instruction selection of global
load/stores in gfx600 due to the lack of FLAT instructions. This patch
fix the crash by selecting MUBUF instructions for global load/stores
in gfx600.

* Rename some tests to try to make a convention (where all components
are optional) of:
<addrspace>_<syncscope>_<memory-orders>_<operation>
* Split up at a level of granularity appropriate for the different RUN
lines (i.e. split on addrspace so GFX6 can avoid FLAT) and that makes
running a specific test reasonable in terms of wall time taken. This
also means when run as part of the test suite the testing is not one
serial bottleneck.
* Auto-generate check lines with `update_llc_test_checks.py` to make
future maintenance more tractable.
