r600/sb: handle jump after target to end of program. (v2)

This fixes hangs on cayman with
tests/spec/arb_tessellation_shader/execution/trivial-tess-gs_no-gs-inputs.shader_test

This has a single if/else in it, and when this peephole activated,
it would set the jump target to NULL if there was no instruction
after the final POP. This adds a NOP if we get a jump in this case,
and seems to fix the hangs, so we have a valid target for the ELSE
instruction to go to, instead of 0 (which causes infinite loops).

v2: update last_cf correctly. (I had some other patches hide this)

mesa/gles: adjust internal format in glTexSubImage2D error checks

When floating point textures are created on OpenGL ES 2.0, driver
is free to choose used internal format. Mesa makes this decision in
adjust_for_oes_float_texture. Error checking for glTexImage2D properly
checks that sized formats are not used. We use same error checking
path for glTexSubImage2D (since there is lot of overlap), however since
those checks include internalFormat checks, we need to pass original
internalFormat passed by the client. Patch adds oes_float_internal_format
that does reverse adjust_for_oes_float_texture to get that format.

nv50/ir: when merging immediates/consts, load directly

When a MERGE operation gets its constraint moves added, it
susbstantially extends live ranges to be reusing an immediate from
earlier in the program (not to mention the silliness of loading an
immediate into a register, and then moving into another register).

We detect these scenarios and insert moves that take the immediate or
constbuf load directly into the register. If it's the last use, then we
can just move that operation to the closer location.

With SM35 (255 regs) we get these results:

freedreno/ir3: add a pass to lower tg4 to txl, enable gather on a4xx

Unfortunately Adreno A4xx hardware returns incorrect results with the
GATHER4 opcodes. As a result, we have to lower to 4 individual texture
calls (txl since we have to force lod to 0). We achieve this using
offsets, including on cube maps which normally never have offsets.

util: Fix disk_cache index calculation on big endian

The cache-test test program attempts to create a collision (using key_a
and key_a_collide) by making the first two bytes identical. The idea is
fine -- the shader cache wants to use the first four characters of a
SHA1 hex digest as the index.

The following program

        unsigned char array[4] = {1, 2, 3, 4};
        int *ptr = (int *)array;

        for (int i = 0; i < 4; i++) {
            printf("%02x", array[i]);
        }
        printf("\n");

        printf("%08x\n", *ptr);

prints

   01020304
   04030201

on little endian, and

   01020304
   01020304

on big endian.

On big endian platforms reading the character array back as an int (as
is done in disk_cache.c) does not yield the same results as reading the
byte array.

To get the first four characters of the SHA1 hex digest when we mask
with CACHE_INDEX_KEY_MASK, we need to byte swap the int on big endian
platforms.

The code defines a macro blk0(i) based on the preprocessor condition
BYTE_ORDER == LITTLE_ENDIAN. If true, blk0(i) is defined as a byte swap
operation. Unfortunately, if the preprocessor macros used in the test
