If the user did not request full linking, link the shader with the
built-in functions, inline them, and eliminate them. Previous to this
you'd see all these calls to "dot" and "max" in the output. This
prevented a lot of expected optimizations and cluttered the output.
This gives it some chance of being useful.
v2: Rebase on top of Ken's "built-ins now" work.
v3: Don't do_common_optimizations if par-linking fails. Update expected
output of warnings tests to prevent 'make check' regressions.
v4: Optimize harder. Most important, do function inlining. Otherwise
it's quite impractical for one function in a file to call another
function in the same file.
v5: Add some code simplifications and an assertion suggested by Iago.

This just makes the output of the standalone compiler a little more
compact.
v2: Fix indexing typo noticed by Iago. Move the add_neg_to_sub_visitor
to it's own header file. Add a unit test that exercises the visitor.
Both the neg_a_plus_b and neg_a_plus_neg_b tests reproduced the bug that
Iago discovered.

So far we have been checking that interface block definitions had matching
matrix layouts by comparing the definitions of their fields, however, this
does not cover the case where the interface blocks are defined with
mismatching matrix layouts but don't define any field with a matrix type.
In this case Mesa will not fail to link because none of the fields will
inherit the mismatching layout qualifier.
This patch fixes the problem in the same way we fixed it for packing layout
information: we add the the layout information to the interface type and then
we check it matches during the uniform block linking process.
v2: Fix unit tests so they pass the new parameter to
glsl_type::get_interface_instance()
Fixes:

This code provides for an on-disk cache of objects. Objects are stored
and retrieved via names that are arbitrary 20-byte sequences,
(intended to be SHA-1 hashes of something identifying for the
content). The directory used for the cache can be specified by means
of environment variables in the following priority order:
$MESA_GLSL_CACHE_DIR
$XDG_CACHE_HOME/mesa
<user-home-directory>/.cache/mesa
By default the cache will be limited to a maximum size of 1GB. The
environment variable:
$MESA_GLSL_CACHE_MAX_SIZE
can be set (at the time of GL context creation) to choose some other
size. This variable is a number that can optionally be followed by
'K', 'M', or 'G' to select a size in kilobytes, megabytes, or
gigabytes. By default, an unadorned value will be interpreted as
gigabytes.
The cache will be entirely disabled at runtime if the variable
MESA_GLSL_CACHE_DISABLE is set at the time of GL context creation.
Many thanks to Kristian Høgsberg <krh@bitplanet.net> for the initial
implementation of code that led to this patch. In particular, the idea
of using an mmapped file, (indexed by a portion of the SHA-1), for the
efficent implementation of cache_has_key was entirely his
idea. Kristian also provided some very helpful advice in discussions
regarding various race conditions to be avoided in this code.

SPIR-V has a concept of a function type that's used fairly heavily. We
could special-case function types in SPIR-V -> NIR but it's easier if we
just add support to glsl_types.

It's a bit more descriptive since it is the base type that you get when you
sample from it. Also, the next commit adds a bare "sampler" type and we
need glsl_type::sampler_type available for a public static member.

All interface blocks will have been lowered by this point so just
use an assert. Returning false would have caused all sorts of
problems if they were not lowered yet and there is an assert to
catch this later anyway.
We also update the tests to reflect this change.
