glsl: don't lower fragdata array if the output data types don't match

Commit 7e414b58640aee6e243d337e72cea290c354f632 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
  7e414b58640aee6 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)

mesa: Restore functionality to dispatch sanity test

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.
