According to GLSL.std.450 spec, SmoothStep expects input to be a
floating-point type, but it does not restrict the bitsize.
Current implementation relies on inputs to be 32-bit.
This commit extends the support to 64-bit size inputs.

Doom shipped with a broken version of GLSLang which handles samplers as
function arguments in a way that isn't spec-compliant. In particular,
it creates a temporary local sampler variable and copies the sampler
into it. While Dave has had a hack patch out for a while that gets it
working, we've never landed it because we've been hoping that a game
update would come out with fixed shaders. Unfortunately, no game update
appears on to be on the horizon and I've found this issue in yet another
application so I think we're stuck working around it. Hopefully, we can
delete this code one day.

Unnamed struct types are now equal across stages based on the fields they
contain, so overriding the type to make sure names match has become
unnecessary.
The check was originally introduced in commit 955c93dc08 ("glsl: Match
unnamed record types across stages.")
v2: clarify the commit message

Previously, if an unnamed and a named struct contained the same fields,
they were considered the same type during linking of globals.
The discussion around commit e018ea81bf ("glsl: Structures must have
same name to be considered same type.") doesn't seem to have considered
this thoroughly, and I see no evidence that an unnamed struct should
ever be considered to be the same type as a named struct.

As a result, unnamed structs defined in different places of the program
are considered the same types if they have the same fields in the same
order.
This will simplify matching of global variables whose type is an unnamed
struct.
It also fixes a memory leak when the same shader containing unnamed
structs is compiled over and over again: instead of creating a new type
each time, the existing type is re-used.
Finally, this does have the effect that some previously rejected programs
are now accepted, such as:
struct {
float a;
} s1;
struct {
float a;
} s2;
s2 = s1;
C/C++ do not allow that, but GLSL does seem to want to treat unnamed
structs with the same fields as the same type at least during linking
(and apparently, some applications require it), so it seems odd to treat
them as different types elsewhere.

This changes the logic during the conversion of the declaration list
struct S {
...
} v;
from AST to IR, but should not change the end result.
When assigning the type of v, instead of looking `S' up in the symbol
table, we read the type from the member variable of ast_struct_specifier.
This change is necessary for the subsequent change to how anonymous types
are handled.
v2: remove a type override when redefining a structure; should be
the same type in that case anyway

By splitting glsl_type::mutex into two, we can avoid dropping the hash
mutex while creating the new type instance (e.g. struct/record,

GLSL ES spec includes the following:
"It is an error to undefine or to redefine a built-in
(pre-defined) macro name."
But desktop GLSL doesn't. This has sparked some discussion
in Khronos, and the final conclusion was to update the
GLSL 4.50 spec to include the following:
"By convention, all macro names containing two consecutive
underscores ( __ ) are reserved for use by underlying
software layers. Defining or undefining such a name in a
shader does not itself result in an error, but may result
in unintended behaviors that stem from having multiple
definitions of the same name. All macro names prefixed
with “GL_” (“GL” followed by a single underscore) are also
reserved, and defining or undefining such a name results in
a compile-time error."
In other words, undefining GL_* names should be an error, but
undefining other names with a double underscore in them is
not strictly prohibited in desktop GLSL.
This patch fixes the preprocessor to apply these rules,
following exactly the implementation already present
in GLSLang. This fixes some tests in CTS.
