3356ac208b ast: Updated AST_NUM_OPERATORS for coherence with ast_operators
AST_NUM_OPERATORS stores the dimension of the ast_operators
enumeration but was not updated after its last modification.

This doesn't add any real modification for any code paths but it makes
sense for coherence.

v2 (Eric Engestrom): Just place the define at the end of the
                     enumeration, not below.

d1f6f65697 glsl: Separate overlapping sentinel nodes in exec_list.
I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.

No difference in OglBatch7 (n=20).

c9afd94af6 glsl: parse new transform feedback layout qualifiers
We reuse the existing offset field for holding the xfb_offset
expression but create a new flag as to avoid hitting the rules
for the offset qualifier for UBOs.

xfb_buffer qualifiers require extra processing when merging as
they can be applied to global out defaults. We just apply the
same rules as we do for the stream qualifier as the spec says:

   "The *xfb_buffer* qualifier follows the same conventions,
    behavior, defaults, and inheritance rules as the qualifier
    stream, and the examples for stream apply here as well."

For xfb_stride we push everything into a global out field for
later processing as xfb_stride applies to the entire buffer.
We still need to have a separate field to store per variable
strides because they can still effect implicit offsets
e.g. when applied to block members with implicit offsets.

8568d02498 glsl: add is_lhs bool on ast_expression
Useful to know if a expression is the recipient of an assignment
or not, that would be used to (for example) raise warnings of
"use of uninitialized variable" without getting a false positive
when assigning first a variable.

By default the value is false, and it is assigned to true on
the following cases:
 * The lhs assignments subexpression
 * At ast_array_index, on the array itself.
 * While handling the method on an array, to avoid the warning
   calling array.length
 * When computed the cached test expression at test_to_hir, to
   avoid a duplicate warning on the test expression of a switch.

set_is_lhs setter is added, because in some cases (like ast_field_selection)
the value need to be propagated on the expression tree. To avoid doing the
propatagion if not needed, it skips if no primary_expression.identifier is
available.

v2: use a new bool on ast_expression, instead of a new parameter
    on ast_expression::hir (Timothy Arceri)

v3: fix style and some typos on comments, initialize is_lhs default value
    on constructor, to avoid a c++11 feature (Ian Romanick)

v4: some tweaks on comments (Timothy Arceri)

78d3098c05 glsl: rework parsing of blocks
Previously interface blocks were giving the global default flags of
uniform blocks. This meant we could not check for invalid qualifiers
on interface blocks because they always contained invalid flags.

This changes parsing so that interface blocks now get an empty
set of layouts.
