Add a enter/leave record callback so that the offset may be aligned to
the proper value. Otherwise only leaf fields are called, and the first
field needs to be aligned to the outer struct's base alignment while the
last field needs to be aligned to the inner struct's base alignment.
This removes most usage of the last field/record type values passed into
visit_field.

Mesa has a shader compiler struct flagging whether GLSL IR's opt_algebraic
and other passes should try and generate certain types of opcodes or
patterns. Extend that to NIR by defining our own struct, which is
automatically generated from the Mesa struct in glsl_to_nir and provided
directly by the driver in TGSI-to-NIR.

This will be used so that we can customize the transforms for the target

we don't actually expect there to be many different conditions (change

opt_copy_propagation and opt_copy_propagation_elements create new ACP
and Kill sets each time they enter a new control flow block. For if
blocks, they also copy the entire existing ACP set contents into the
new set.
When we exit the control flow block, we discard the new sets. However,
we weren't freeing them - so they lived on until the pass finished.
This can waste a lot of memory (57MB on one pessimal shader).
This patch makes the pass allocate ACP entries using this->acp as the
memory context, and Kill entries out of this->kill. It also steals
kill entries when moving them from the inner kill list to the parent.
It then frees the lists, including their contents.
v2: Move ralloc_free(this->acp) just before this->acp = orig_acp
(suggested by Eric Anholt).

Looking at one of these examples (tesseract), it's from vec4 load_consts
for a MRT solid fill, which do get CSEed now that we don't memcmp off the
end of the const value and into the SSA def. For the 1-component loads
that are common in i965, we were only memcmping off into the rest of the
usually zero-filled const_value.
