This change did not introduce new piglit quick.test regressions on an Ivybridge Mobile and a GM45 Express chipset.

| | | | | | | | | | | | | | | | Most of the dirty flags were listed in some arbitrary order. Some used bonus parenthesis. Some put multiple flags on one line, others put one per line. Some used tabs instead of spaces...but only on some lines. This patch settles on one flag per line, in alphabetical order, using spaces instead of tabs, and sheds the unnecessary parentheses. Sorting was mostly done with vim's visual block feature and !sort, although I alphabetized short lists by hand; it was pretty manual.

| | | | | | | | | | | | | | | | | | For a long time, we've wanted a place to put utility code which isn't directly tied to Mesa or Gallium internals. This patch creates a new src/util directory for exactly that purpose, and builds the contents as libmesautil.la. ralloc seemed like a good first candidate. These days, it's directly used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl didn't make much sense.

| | | | | | | | | | | | | | | | Will be used to print disassembly after jump targets are set and instructions are compacted, while still retaining higher-level IR annotations and basic block information. An array of 'struct annotation' will live along side the generated assembly.

The old terminology, "vert_result", was confusing because (a) it referred to the enum gl_vert_result, which no longer exists (it was replaced with gl_varying_slot), and (b) it implied a vertex output, but with the advent of geometry shaders, it could be either a vertex or a geometry output, depending what shaders are in use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add the support of gl_PointCoord gl builtin variable for platform gen4 and gen5(ILK). Unlike gen6+, we don't have a hardware support of gl_PointCoord, means hardware will not calculate the interpolation coefficient for you. Instead, you should handle it yourself in sf shader stage. But badly, gl_PointCoord is a FS instead of VS builtin variable, thus it's not included in c.vue_map generated in VS stage. Thus the current code doesn't aware of this attribute. And to handle it correctly, we need add it to c.vue_map manually to let SF shader generate the needed interpolation coefficient for FS shader. SF stage has it's own copy of vue_map, thus I think it's safe to do it manually. Since handling gl_PointCoord for gen4 and gen5 platforms is somehow a little special, I added a lot of comments and hope I didn't overdo it ;) v2: add a /* _NEW_BUFFERS */ comment to note the state flag dependency and also add the _NEW_BUFFERS dirty mask (Eric).

| | | | | | | | | | | | | | | | The i965 driver already had a function to count bits in a 64-bit uint (brw_count_bits()), but it was buggy (it only counted the bottom 32 bits) and it was clumsy (it had a strange and broken fallback for non-GCC-like compilers, which fortunately was never used). Since Mesa already has a _mesa_bitcount() function, it seems better to just create a _mesa_bitcount_64() function rather than special-case this in the i965 driver.
