meta: Add GLSL variant of _mesa_meta_GenerateMipmap() function

This reduces the overhead of using the fixed function internally
in the driver.

V2: Use setup_glsl_generate_mipmap() and setup_ff_generate_mipmap()
    functions to avoid code duplication.
    Use glsl version when ARB_{vertex, fragmet}_shader are present.
    Remove redundant code.

V3: Remove redundant border related code leaving the assertion.

radeon/llvm: Mark M0 as a def when lowering interpolation instructions
radeon/llvm: Declare the interpolation intrinsics as ReadOnly

This signals to the Dead Code Elimination pass that it is safe to
remove these instructions when they are dead.
radeon/llvm: Set the neverHasSideEffects bit on more instructions

This flag makes these instructions candidates for the dead code
elimination and common subexpression elimination.
radeon/llvm: Create a register class for the M0 register

The Common Subexpression Elimination pass will not operate on
instructions with physical register defs, so we end up with
several redundant copies to M0 when using interpolation.

Adding a register class that only contains the M0 register allows
use to use a virtual register to represent M0, and makes it possible
for the Common Subexpression Elimination pass to remove the extra
copies.

mesa/es: Validate glFramebufferTexture2D textarget in Mesa code rather than the ES wrapper

v2: Add proper core-profile and GLES3 filtering.

v3: Change !_mesa_is_desktop_gl tests to _mesa_is_gles test.  The test
around GL_TEXTURE_2D_ARRAY got some other changes because that enum is
also available with GLES3 (which uses API_OPENGLES2).  Based on review
feedback from Eric Anholt.
