This adds the builtins and the lexer support.

To avoid too many warnings, it adds basic support to the type in a few

It also adds a query to be used later for if a type is an integer 32 or 64.

Emil Velikov d1efa09d34 util: import sha1 implementation from OpenBSD
At the moment we support 5+ different implementations each with varying
amount of bugs - from thread safely problems [1], to outright broken
implementation(s) [2]

In order to accommodate these we have 150+ lines of configure script and
extra two configure toggles. Whist an actual implementation being
~200loc and our current compat wrapping ~250.

Let's not forget that different people use different code paths, thus
effectively makes it harder to test and debug since the default
implementation is automatically detected.

To minimise all these lovely experiences, import the "100% Public
Domain" OpenBSD sha1 implementation. Clearly document any changes needed
to get building correctly, since many/most of those can be upstreamed
making future syncs easier.

As an added bonus this will avoid all the 'fun' experiences trying to
integrate it with the Android and SCons builds.

v2: Manually expand __BEGIN_DECLS/__END_DECLS and document (Tapani).

Furthermore it seems that some games (or surrounding runtime) static
link against OpenSSL resulting in conflicts. For more information see
the discussion thread [3]

Kenneth Graunke e7d4008ebf glsl: Make copy propagation not panic when it sees an intrinsic.
A number of games have large arrays of constants, which we promote to
uniforms.  This introduces copies from the uniform array to the original
temporary array.  Normally, copy propagation eliminates those copies,
making everything refer to the uniform array directly.

A number of shaders in "Deus Ex: Mankind Divided" recently exposed a
limitation of copy propagation - if we had any intrinsics (i.e. image
access in a compute shader), we weren't able to get rid of these copies.

That meant that any variable indexing remained on the temporary array
rather being moved to the uniform array.  i965's scalar backend
currently doesn't support indirect addressing of temporary arrays,
which meant lowering it to if-ladders.  This was horrible.

According to Marek, on radeonsi/GCN, "F1 2015" uses 64% less
spilled-temp-array memory.

On i965/Skylake:

total instructions in shared programs: 13362954 -> 13329878 (-0.25%)
instructions in affected programs: 43745 -> 10669 (-75.61%)

total cycles in shared programs: 248081010 -> 245949178 (-0.86%)

Helps Deus Ex: Mankind Divided.   The one shader with hurt spills/fills
is from Tomb Raider at Ultra settings, but that same shader has a
-39.55% reduction in instructions and -14.09% reduction in cycle counts,
so it seems like a win there as well.

This fixes a bug in code motion that occurred when the best block is the
same as the schedule early block.  In this case, because we're checking
(lca != def->parent_instr->block) at the top of the loop, we never get to
the check for loop depth so we wouldn't move it out of the loop.  This
commit reworks the loop to be a simple for loop up the dominator chain and
we place the (lca != def->parent_instr->block) check at the end of the

Jason Ekstrand 27a1c7ffbd spirv: Handle patch decorations up-front
Once again, SPIR-V is insane... It allows you to place "patch"
decorations on structure members.  Presumably, this is so that you can
do something such as

out struct S {
   layout(location = 0) patch vec4 thing1;
   layout(location = 0) vec4 thing2;
} str;

And have your I/O "nicely" organized.  While this is a bit silly, it's
allowed and well-defined so whatever.  Where it really gets interesting
is when you have an array of struct.  SPIR-V says nothing about not
allowing you to have those qualifiers on the members of a struct that's
inside an array and GLSLang does this.  Specifically, if you have

layout(location = 0) out patch struct S {
   vec4 thing1;
   vec4 thing2;
} str[2];

then GLSLang will place the "patch" decorations on the struct members.
This is ridiculous there is no way that having some of them be patch and
some not would be well-defined given that patch and non-patch outputs
are in effectively different storage classes.  This commit moves around
the way we handle the "patch" decoration so that we can detect even the
crazy cases and handle them.

Kenneth Graunke 5edc338162 compiler: Merge shader_info's tcs and tes structs.
Annoyingly, SPIR-V lets you specify all of these fields in either the
TCS or TES, which means that we need to be able to store all of them
for either shader stage.  Putting them in a union won't work.

Combining both is an easy solution, and given that the TCS struct only
had a single field, it's pretty inexpensive.

This patch renames the combined struct to "tess" to indicate that it's
for tessellation in general, not one of the two stages.
