The backend_shader class really is a representation of a shader. The fact
that it inherits from ir_visitor is somewhat immaterial.

I used these in the SEL peephole, but they require extra tracking and
fix ups. The SEL peephole can pretty easily find the blocks it needs
without these.

The dump() methods don't alter the CFG or basic blocks, so we should
mark them as const. This lets you call them even if you have a const
cfg_t - which is the case in certain portions of the code (such as live
interval handling).

... rather than pointing directly to the associated instruction. This
will let us set the block containing the IF statement's else-pointer to
NULL, when we delete a useless ELSE instruction, as in the case
(+f0) if(8)
...
else(8)
endif(8)
Also, remove the pointer to the ENDIF, since it's unused, and it was
also potentially wrong, in the case of a basic block containing both an
ENDIF and an IF instruction:
endif(8)
cmp.ne.f0(8) ...
(+f0) if(8)

Use this as an opportunity to rename 'block_num' to 'num'. block->num is
clear, and block->block_num has always been redundant.

The next patch adds a foreach_block (block, cfg) macro, which works
better if it provides a direct bblock_t pointer, rather than a
bblock_link pointer that you have to use to find the actual block.

make_list is just a one-line wrapper and was confusingly called by
NULL objects. E.g., cur_if == NULL; cur_if->make_list(mem_ctx).

The cfg_t object relies on the memory allocator zeroing out its
contents before it's initialized, which is quite an unusual practice
in the C++ world because it ties objects to some specific allocation
scheme, and gives unpredictable results when an object is created with
a different allocator -- Stack allocation, array allocation, or
aggregation inside a different object are some of the useful
possibilities that come to my mind. Initialize all fields from the
constructor and stop using the zeroing allocator.

v2: Use zero initialization for numeric types instead of default construction.

These classes declared a placement new operator, but didn't declare a
delete operator. Switching to the macro gives them a delete operator,
which probably is a good idea anyway.
This also eliminates a lot of boilerplate.
v2: Properly use RZALLOC in Mesa IR/TGSI translators. Caught by Eric
and Chad.

All we really need is a memory context and the instruction list; passing
a backend_visitor is just convenient at times.
This will be necessary two patches from now.
