HLSL: allow "sample" in expressions.

Unlike other qualifiers, HLSL allows "sample" to be either a qualifier keyword or an
identifier (e.g, a variable or function name).

A fix to allow this was made a while ago, but that fix was insufficient when 'sample'
was used in an expression.  The problem was around the initial ambiguity between:

   sample float a; // "sample" is part of a fully specified type
and
   sample.xyz;     // sample is a keyword in a dot expression

Both start the same.  The "sample" was being accepted as a qualifier before enough
further parsing was done to determine we were not a declaration after all.  This
consumed the token, causing it to fail for its real purpose.

Now, when accepting a fully specified type, the token is pushed back onto the stack if
the thing is not a fully specified type.  This leaves it available for subsequent
purposes.

Changed the "hlsl.identifier.sample.frag" test to exercise this situation, distilled
down from a production shaders.

HLSL: Recursive composite flattening

This PR implements recursive type flattening.  For example, an array of structs of other structs
can be flattened to individual member variables at the shader interface.

This is sufficient for many purposes, e.g, uniforms containing opaque types, but is not sufficient
for geometry shader arrayed inputs.  That will be handled separately with structure splitting,
 which is not implemented by this PR.  In the meantime, that case is detected and triggers an error.

The recursive flattening extends the following three aspects of single-level flattening:

- Flattening of structures to individual members with names such as "foo[0].samp[1]";

- Turning constant references to the nested composite type into a reference to a particular
  flattened member.

- Shadow copies between arrays of flattened members and the nested composite type.

Previous single-level flattening only flattened at the shader interface, and that is unchanged by this PR.
Internally, shadow copies are, such as if the type is passed to a function.

Also, the reasons for flattening are unchanged.  Uniforms containing opaque types, and interface struct
types are flattened.  (The latter will change with structure splitting).

One existing test changes: hlsl.structin.vert, which did in fact contain a nested composite type to be
flattened.

Two new tests are added: hlsl.structarray.flatten.frag, and hlsl.structarray.flatten.geom (currently
issues an error until type splitting is online).

The process of arriving at the individual member from chained postfix expressions is more complex than
it was with one level.  See large-ish comment above HlslParseContext::flatten() for details.

HLSL: opcode specific promotion rules for interlocked ops

PR #577 addresses most but not all of the intrinsic promotion problems.
This PR resolves all known cases in the remainder.

Interlocked ops need special promotion rules because at the time
of function selection, the first argument has not been converted
to a buffer object.  It's just an int or uint, but you don't want
to convert THAT argument, because that implies converting the
buffer object itself.  Rather, you can convert other arguments,
but want to stay in the same "family" of functions.  E.g, if
the first interlocked arg is a uint, use only the uint family,
never the int family, you can convert the other args as you please.

This PR allows making such opcode and arg specific choices by
passing the op and arg to the convertible lambda.  The code in
the new test "hlsl.promote.atomic.frag" would not compile without
this change, but it must compile.

Also, it provides better handling of downconversions (to "worse"
types), which are permitted in HLSL.  The existing method of
selecting upconversions is unchanged, but if that doesn't find
any valid ones, then it will allow downconversions.  In effect
this always uses an upconversion if there is one.

steve-lunarg [Wed, 2 Nov 2016 18:42:34 +0000 (12:42 -0600)]
HLSL: add intrinsic function implicit promotions

This PR handles implicit promotions for intrinsics when there is no exact match,
such as for example clamp(int, bool, float).  In this case the int and bool will
be promoted to a float, and the clamp(float, float, float) form used.

These promotions can be mixed with shape conversions, e.g, clamp(int, bool2, float2).

Output conversions are handled either via the existing addOutputArgumentConversion
function, which this PR generalizes to handle either aggregates or unaries, or by
intrinsic decomposition.  If there are methods or intrinsics to be decomposed,
then decomposition is responsible for any output conversions, which turns out to
happen automatically in all current cases.  This can be revisited once inout
conversions are in place.

Some cases of actual ambiguity were fixed in several tests, e.g, spv.register.autoassign.*

Some intrinsics with only uint versions were expanded to signed ints natively, where the
underlying AST and SPIR-V supports that.  E.g, countbits.  This avoids extraneous
conversion nodes.

A new function promoteAggregate is added, and used by findFunction.  This is essentially
a generalization of the "promote 1st or 2nd arg" algorithm in promoteBinary.

The actual selection proceeds in three steps, as described in the comments in
hlslParseContext::findFunction:

1. Attempt an exact match.  If found, use it.
2. If not, obtain the operator from step 1, and promote arguments.
3. Re-select the intrinsic overload from the results of step 2.

HLSL: use HLSL parser to parse HLSL intrinsic prototypes, enable int/bool mats

to create a language specific built in parser.  (This code was present before
but not encapsualted in a fn).  This can now be used to create a source language
specific parser for builtins.

Along with this, the code creating HLSL intrinsic prototypes can now produce
them in HLSL syntax, rather than GLSL syntax.  This relaxes certain prior
restrictions at the parser level.  Lower layers (e.g, SPIR-V) may still have
such restrictions, such as around Nx1 matrices: this code does not impact
that.

This PR also fleshes out matrix types for bools and ints, both of which were
partially in place before.  This was easier than maintaining the restrictions
in the HLSL prototype generator to avoid creating protoypes with those types.

to "temp".
