Commit 7e414b5864 broke the gl_FragData array
into separate gl_FragData[i] variables, so drivers can eliminate useless
writes to gl_FragData improving their performance.
The problem occurs when GLSL IR code is linked in the following case:
* The FS output variable base data type does not match gl_FragData one (float
vector)
* The FS output variable is replaced by gl_out_FragDataX because of commit
7e414b5864 with X from 0 to GL_MAX_DRAW_BUFFERS.
Then the FS output variable base data type is lost in the resulting GLSL IR,
making that the driver does a wrong assignment to gl_out_FragData components
because of unmatching data types.
This patch reverts the fragdata array lowering when the output var base data type
doesn't match gl_out_FragData, i.e., when output variable base data type is
not a float or a float vector.
This patch fixes 250 dEQP tests (tested in an Intel Haswell machine)
dEQP-GLES3.functional.fragment_out.random.* (22 failed tests)
dEQP-GLES3.functional.fragment_out.array.uint.* (120 failed tests)
dEQP-GLES3.functional.fragment_out.array.int.* (108 failed tests)

On Skylake it is possible to choose your own alignment values for
compressed textures but they are expressed as a multiple of the block
size. The minimum alignment value we can use is 4 so we effectively
have to align to 4 times the block size. This patch makes it initially
set mt->align_[wh] to the large alignment value and then later divides
it by the block size so that it can be uploaded as part of the surface
state.

Along with a couple secondary goals, the dispatch sanity test had two
major, primary goals.
1. Ensure that all functions part of an API version are set in the
dispatch table.
2. Ensure that functions that cannot be part of an API version are not
set in the dispatch table.
Commit 4bdbb58 removed the tests ability to fulfill either of its
primary goals by removing anything that used _mesa_generic_nop(). It
seems like the problem on Windows could have been resolved by adding the
NULL context pointer check from nop_handler to _mesa_generic_nop().
There is, however, some debugging benefit to actually getting the
(supposed) function name logged in the "unsupported function called"
message.
The preceding commit added a function, _glapi_new_nop_table, that
allocates a table of per-entry point no-op functions. Restore the
ability to actually validate the sanity of the dispatch table by using
_glapi_new_nop_table.
Previous to this commit removing a function from one of the
*_functions_possible lists would not cause the test to fail. With this
commit removing such a function will result in failure, as is expected.

This instruction calculates the index of an arbitrary channel enabled
in the current execution mask. It's expected to be used as input for
the BROADCAST opcode, but it's implemented as a separate instruction
rather than being baked into BROADCAST because FIND_LIVE_CHANNEL has
no dependencies so it can always be CSE'ed with other instances of the
same instruction within a basic block.
v2: Whitespace fixes.

The BROADCAST instruction picks the channel from its first source
given by an index passed in as second source. This will be used in
situations where all channels from the same SIMD thread have to agree
on the value of something, e.g. a surface binding table index.
This is in particular the case for UBO, sampler and image arrays,
which can be indexed dynamically with the restriction that all active
SIMD channels access the same index, provided to the shared unit as
part of a single scalar field of the message descriptor. Simply
taking the index value from the first channel as we were doing until
now is incorrect, because it might contain an uninitialized value if
the channel had previously been disabled by non-uniform control flow.
v2: Minor style fixes. Improve commit message.
