1f47f78fc3 glcpp: Update tests for new #undef of built-in macro rules.
Ian recently changed the preprocessor to allow this in most GLSL
versions, but not GLSL ES 3.00+.  This patch converts the existing
test that expects a failure to a #version 300 es shader, and adds
a #version 110 shader to make sure that it's allowed.

a32c87f74b glsl: emit a specific error when ast_*_assign changes type
For regular ast_add, we can implicitly change either a or b's type.
However in an assignment situation, the type of the lvalue is fixed. So
if the implicit conversion logic decides to change it, it means that the
rhs's type could not be converted to the lhs type.

Emit a specific error for this rather than the rather mysterious "is not
an lvalue" error that results from having a i2f or other operation as
the lvalue.

1baae00089 glsl: look for frag data bindings with [0] tacked onto the end for arrays
The GL spec is very unclear on this point. Apparently this is discussed
without resolution in the closed Khronos bugtracker at
https://cvs.khronos.org/bugzilla/show_bug.cgi?id=7829 . The
recommendation is to allow dropping the [0] for looking up the bindings.

The approach taken in this patch is to instead tack on [0]'s for each
arrayness level of the output's type, and doing the lookup again. That
way, for

out vec4 foo[2][2][2]

we will end up looking for bindings for foo, foo[0], foo[0][0], and
foo[0][0][0], in that order of preference.

f9f462936a glsl: Fix invariant matching in GLSL 4.30 and GLSL ES 1.00.
Old languages (GLSL <= 4.20 and GLSL ES 1.00) require "invariant"
to be specified on both inputs and outputs, and match when linking.

New languages only allow outputs to be qualified as "invariant"
and remove the "invariant must match" restriction when linking
varyings (because no input can have that qualifier).

Commit 426a50e208 introduced the new
behavior for ES 3.00.  It also removed the "must match" restriction
for ES 1.00 shaders, which I believe is incorrect.  This patch adds
that back, as well as making 4.30+ follow the new rules.

Thanks to Qiankun Miao for noticing this discrepancy.

0ed316360f glsl: Tidy stream handling in merge_qualifier().
The previous commit fixed xfb_buffer handling, which was largely copy
and pasted from the stream handling.  The difference is that stream
was set in input_layout_mask, so it worked.

However, that's totally rubbish: stream is only valid on geometry shader
outputs.  Presumably this was to hack around inout.  Instead, apply the
solution I used in the previous fix.

Really, we just need to separate shader interface and parameter
qualifier handling so this isn't a mess, but this patch at least
tidies it slightly.

dffa371665 glsl: Fix inout qualifier handling in GLSL 4.40.
inout variables have q.in and q.out set.  We were trying to set
xfb_buffer = 1 for shader output variables (and inadvertantly setting
it on inout parameters, too).  But input_layout_mask doesn't have
xfb_buffer set, so it was seen as in invalid input qualifier.

This meant that all 'inout' parameters were broken.

50b49d242d glcpp: Only disallow #undef of pre-defined macros on GLSL ES >= 3.00 shaders
Section 3.4 (Preprocessor) of the GLSL ES 3.00 spec says:

   It is an error to undefine or to redefine a built-in (pre-defined)
   macro name.

The GLSL ES 1.00 spec does not contain this text.

Section 3.3 (Preprocessor) of the GLSL 1.30 spec says:

   #define and #undef functionality are defined as is standard for C++
   preprocessors for macro definitions both with and without macro
   parameters.

At least as far as I can tell GCC allow '#undef __FILE__'.  Furthermore,
there are desktop OpenGL conformance tests that expect '#undef
__VERSION__' and '#undef GL_core_profile' to work.

Fixes:

    GL45-CTS.shaders.preprocessor.definitions.undefine_version_vertex
    GL45-CTS.shaders.preprocessor.definitions.undefine_version_fragment
    GL45-CTS.shaders.preprocessor.definitions.undefine_core_profile_vertex

1443c10d74 glsl: struct constructors/initializers only allow implicit conversions
When an argument for a structure constructor or initializer doesn't
match the expected type, only Section 4.1.10 “Implicit Conversions”
are allowed to try to match that expected type.

From page 32 (page 38 of the PDF) of the GLSL 1.20 spec:

  " The arguments to the constructor will be used to set the structure's
    fields, in order, using one argument per field. Each argument must
    be the same type as the field it sets, or be a type that can be
    converted to the field's type according to Section 4.1.10 “Implicit
    Conversions.”"

From page 35 (page 41 of the PDF) of the GLSL 4.20 spec:

  " In all cases, the innermost initializer (i.e., not a list of
    initializers enclosed in curly braces) applied to an object must
    have the same type as the object being initialized or be a type that
    can be converted to the object's type according to section 4.1.10
    "Implicit Conversions". In the latter case, an implicit conversion
    will be done on the initializer before the assignment is done."

v2: Remove also the now redundant constant conversion, the
    constant_record_constructor helper and the replacement code
    (Timothy).
