Indexing nodes now get their type set in TIntermBinary::promote, same
as math and logic ops. They are also constant folded through
TIntermBinary::fold() instead of having special functions for constant
folding them in ParseContext.

Index nodes for struct and interface block member access now always
have integer type, instead of sometimes having the type of the field
they were used to access.

Usage of TIntermBinary constructor is cleaned up so only the
constructor that takes in left and right operands is used. The type
of TIntermBinary nodes is always determined automatically.

Together these changes make the code considerably cleaner.

Note that the code for constant folding for array indexing is actually
never hit because constant folding array constructors is still
intentionally disabled in the code.

Prefer asserts instead of adding internal errors to the compiler log
when types of arguments are not as expected or the folding function
runs into an operation it can't handle. Neither of these cases should
be possible, the checks for correct argument types are solid at this
point.

In the future, when new built-in functions are added, constant folding
support for them should be added as well.

foldUnaryWithDifferentReturnType and foldUnaryWithSameReturnType are
renamed to foldUnaryNonComponentWise and foldUnaryComponentWise
respectively. These names better reflect what these functions are
doing.

The info sink member is removed from TIntermediate, since TDiagnostics
is now passed into the functions that may generate warnings instead.

The grammar has been changed so that ES31 grammar is followed more
closely. The ES31 grammar is not fully supported, only functionality
related to qualifier enumeration is added.

The ParseContext is changed so that type qualifiers can be now joined
together (i.e. like layout qualifiers). This will allow enumeration of
multiple storage qualifiers (i.e. uniform readonly coherent) which is
essential for support of ES31 features.

Some of the error checks had to be moved closer to the root of the
parse tree since some of the information about the expression might be
missing.

Unfortunately, as there is no explicit ordering imposed by the
grammar, additional checks for proper order of qualifiers had to be
added. I also included unit tests which test against malformed
shaders.
