TARGET_CC is not defined for the secondary arch on combined 32/64-bit

compiler/glsl: Fix uniform location counting.

This patch moves the calculation of current uniforms to
link_uniforms, which makes use of UniformRemapTable which
stores all the reserved uniform locations.

Location assignment for implicit uniforms now tries to use
any gaps left in the table after the location assignment
for explicit uniforms. This gives us more space to store more
uniforms.

Patch is based on earlier patch with following changes/additions:

   1: Move the counting of explicit locations to
      check_explicit_uniform_locations and then pass
      the number to link_assign_uniform_locations.
   2: Count the number of empty slots in UniformRemapTable
      and store them in a list_head.
   3: Try to find an empty slot for implicit locations from
      the list, if that fails resize UniformRemapTable.

This improves the performance of applications which use glXUseXFont()

Basically, we collect all the glBitmap images from the display lists

glCallLists() command, we render a set of textured quads where each
quad is textured with one bitmap image.  Actually, the rendering part
has to be done by the Mesa driver or Mesa/gallium state tracker.

Handle removal of LLVMAddTargetData in SVN revision 260919

LLVM removed LLVMAddTargetData for the 3.9 release in r260919.  For the two
places in mesa where this is called, only enable the lines when compiling

For the radeon driver, I'm not sure how to check if any other LLVM calls need
