nir: Get rid of *_indirect variants of input/output load/store intrinsics

There is some special-casing needed in a competent back-end.  However, they
can do their special-casing easily enough based on whether or not the
offset is a constant.  In the mean time, having the *_indirect variants
adds special cases a number of places where they don't need to be and, in
general, only complicates things.  To complicate matters, NIR had no way to
convdert an indirect load/store to a direct one in the case that the
indirect was a constant so we would still not really get what the back-ends
wanted.  The best solution seems to be to get rid of the *_indirect
variants entirely.

blit: Don't take into account the Mesa format when checking MSRT blit

According to the GLES3 spec, blitting between multisample FBOs with
different internal formats should not be allowed. The
compatible_resolve_formats function implements this check. Previously
it had a shortcut where if the Mesa formats of the two renderbuffers
were the same then it would assume the blit is ok. However some
drivers map different internal formats to the same Mesa format, for
example it might implement both GL_RGB and GL_RGBA textures with
MESA_FORMAT_R8G8B8A_UNORM. The function is used to generate a GL error
according to what the GL spec requires so the blit should not be
allowed in that case. This patch just removes the shortcut so that it
only ever looks at the internal format.

Note that I posted a related patch to disable this check altogether
for desktop GL. However this function is still used on GLES3 because
there are conformance tests that require this behaviour so this patch
is still useful.

the render surface format is being overriden to a different format
than the one used for texturing. The one used for texturing is not
actually a renderable format. It arguably makes sense that the sampler
hardware doesn't handle the fast color correctly in these cases
because it shouldn't be possible to end up with a fast cleared surface

support compute shader shared variables.)

v2:
