gallium: fix u_default_transfer_inline_write for textures

This doesn't fix any known issue. In fact, radeon drivers ignore all
the discard flags for textures and implicitly do "discard range"
for any write transfer.

glsl: Fix the foreach_in_list_reverse macro.

We clearly don't want to start at the head and walk backwards; we want
to start at the last real element before the tail sentinel.  If the list
is empty, tail_pred will be the head sentinel, and we'll stop.

Nothing uses this function, so I guess nobody noticed it was broken.

nv50/ir: use unordered_set instead of list to keep track of var uses

The set of variable uses does not need to be ordered in any way, and
removing/adding elements is a fairly common operation in various
optimization passes.

This shortens runtime of piglit test fp-long-alu to ~22s from ~4h

glsl/glcpp: Fix preprocessor error condition for macro redefinition

This patch specifically fixes redefinition condition for white space
changes. #define and #undef functionality in GLSL follows the standard
for C++ preprocessors for macro definitions.

From https://gcc.gnu.org/onlinedocs/cpp/Undefining-and-Redefining-Macros.html:

These definitions are effectively the same:

     #define FOUR (2 + 2)
     #define FOUR         (2    +    2)
     #define FOUR (2 /* two */ + 2)

but these are not:

     #define FOUR (2 + 2)
     #define FOUR ( 2+2 )
     #define FOUR (2 * 2)
     #define FOUR(score,and,seven,years,ago) (2 + 2)

glsl/glcpp: Fixup glcpp tests for redefining a macro with whitespace changes.

Previously, the test suite was expecting the compiler to allow a redefintion
of a macro with whitespace added, but gcc is more strict and allows only for
changes in the amounts of whitespace, (but insists that whitespace exist or
not in exactly the same places).

See: https://gcc.gnu.org/onlinedocs/cpp/Undefining-and-Redefining-Macros.html:

 These definitions are effectively the same:

      #define FOUR (2 + 2)
      #define FOUR         (2    +    2)
      #define FOUR (2 /* two */ + 2)

 but these are not:

      #define FOUR (2 + 2)
      #define FOUR ( 2+2 )
      #define FOUR (2 * 2)
      #define FOUR(score,and,seven,years,ago) (2 + 2)

This change adjusts the existing "redefine-macro-legitimate" test to work with
the more strict understanding, and adds a new "redefine-whitespace" test to
verify that changes in the position of whitespace are flagged as errors.

glsl/glcpp: Fix glcpp to catch garbage after #if 1 ... #else

Previously, a line such as:

	#else garbage

would flag an error if it followed "#if 0", but not if it followed "#if 1".

We fix this by setting a new bit of state (lexing_else) that allows the lexer
to defer switching to the <SKIP> start state until after the NEWLINE following
the #else directive.

A new test case is added for:

	#if 1
	#else garbage
	#endif

which was untested before, (and did not generate the desired error).

This fixes the following Khronos GLES3 CTS tests:

	tokens_after_else_vertex
        tokens_after_else_fragment
