We can now pass (sm<4) and (sm>=4) to "fail" and "todo" qualifiers, and
we can use multiple of these qualifier arguments using "&" for AND and
"|" for OR.
examples:
todo(sm>=4 & sm<6)
todo(sm<4 | sm>6)
parenthesis are not supported.
Adding additional model ranges for the tests, if we need them, should be
easier now, since they only have to be added to the "valid_args" array.
Currently, if a probe fails, it will print the line number of the [test]
block the probe is in, not the line number of the probe itself. This
makes it somewhat difficult to debug.
This commit makes it print the line number that a test fails at.
The location of dxcompiler should be set during configuration with
'DXCOMPILER_LIBS=-L/path/to/dxcompiler', and then at runtime with
LD_LIBRARY_PATH, WINEPATH or PATH as applicable.
A new 'fail(sm<6)' decoration is needed on many shader declarations
because dxcompiler succeeds on many shaders which fail with fxc. The
opposite case is less common and is flagged with 'fail(sm>=6)'. A few
tests cause dxcompiler to crash or hang, so these are avoided using
[require], which now skips tests until reset instead of exiting. Also,
'todo(sm<6)' and 'todo(sm>=6)' are used to separate checking of results.
