While ~loop_state() is already freeing the loop_variable_state objects
via ralloc_free(this->mem_ctx), the ~loop_variable_state() destructor
was never getting called, so the hash table inside loop_variable_state

Fixes a memory leak in any shader with loops.

OpenGL allows you to declare user-defined fragment shader outputs with
less than four components:
out ivec2 color;
This makes sense if you're rendering to an RG format render target.
Previously, we assumed that all color outputs had four components (like
the built-in gl_FragColor/gl_FragData variables). This caused us to
call emit_color_write for invalid indices, incrementing the output
virtual GRF's reg_offset beyond the size of the register.
This caused cascading failures: split_virtual_grfs would allocate new
size-1 registers based on the virtual GRF size, but then proceed to
rewrite the out-of-bounds accesses assuming that it had allocated enough
new (contiguously numbered) registers. This resulted in instructions
that accessed size-1 GRFs which register numbers beyond
virtual_grf_next (i.e. registers that were never allocated).
Finally, this manifested as live variable analysis and instruction
scheduling accessing their temporary array with an out of bounds index
(as they're all sized based on virtual_grf_next), and the program would
segfault.
It looks like the hardware's Render Target Write message requires you to
send four components, even for RT formats such as RG or RGB. This patch
continues to use all four MRFs, but doesn't bother to fill any data for
the last few, which should be unused.

Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also
accidentally added a new pointer to the enclosing loop. Furthermore, it
tried to initialize the new field by adding "this->loop = loop;" to the
constructor, but since there is no loop parameter, this only initialized
the field to itself---so it will likely be a garbage pointer.
A lot of code, such as lower_jumps, allocates new loop jumps without
setting this field appropriately, so any uses would probably just crash.
Thankfully, there were none, so we can just delete the field.

With the old function we didn't make that distinction and generated

This patch removes ARB_framebuffer_object from the GLES1 and GLES2
extension lists in intel_extensions_es.c.
Fixes a crash in the Android browser on Ice Cream Sandwich.
The Android browser crashed because it did the following, which is legal
in GLES2 but not in ARB_framebuffer_object.
glGenFramebuffers(1, &fb);
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// render render render...
glDeleteFramebuffers(1, &fb);
// go do other stuff...
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// This bind unexpectedly failed, and the app panics.
The semantics of glBindFramebuffer specified by ARB_framebuffer_object (a
desktop GL extension) and GLES2 specs are incompatible. The ideal solution
to fix this is to create separate API entry points for glBindFramebuffer,
one for GL and the other for GLES2. But, until that work is complete,
disabling ARB_framebuffer_object in GLES2 contexts safely fixes the problem.
Likewise, the semantics of glBindFramebuffer in ARB_framebuffer_object and
of glBindFramebufferOES in OES_framebuffer_object (a GLES1 extension) are
incompatible. Even though the functions have different names, the semantic
difference still results in a bug because both API calls are implemented
by a single function, _mesa_BindFramebufferEXT, which handles the semantic
difference incorrectly. Again, disabling ARB_framebuffer_object in GLES1
contexts safely fixes this problem.
According to the ARB_framebuffer_object spec, the extension is an
amalgamation of
EXT_framebuffer_object
EXT_framebuffer_blit
EXT_packed_depth_stencil
EXT_framebuffer_multisample
By disabling this extension, however, no functionality is removed from
GLES1 and GLES2 contexts because 1) the first three extensions are
explicitly enabled in Intel's ES extension lists and 2) no functionality
of the last extension is exposed in an ES context.
Note: This is a candidate for the 8.0 branch.
