Since the vec4_visitor and vec4_generator classes are going to be
re-used for geometry shaders, we can't enable their debug
functionality based on (INTEL_DEBUG & DEBUG_VS) anymore. Instead, add
a debug_flag boolean to these two classes, so that when they're
instantiated the caller can specify whether debug dumps are needed.

Geometry shader inputs are arrays, but they use an unusual array
layout: instead of all array elements for a given geometry shader
input being stored consecutively, all geometry shader inputs are
interleaved into one giant array. As a result, the array stride we
use to access geometry shader inputs must be equal to the size of the
input VUE, rather than the size of the array element.
This patch introduces a new virtual function,
vec4_visitor::compute_array_stride(), which will allow geometry shader
compilation to specialize the computation of array stride to account
for the unusual layout of geometry shader input arrays. It also
renames the local variable that the ir_dereference_array visitor uses
to store the stride, to avoid confusion.

This patch introduces a new function, vec4_visitor::emit_vertex(),
which contains the code for emitting vertices that will need to be
common between the vertex and geometry shaders.
Geometry shaders will need to use a different message header, and a
different opcode, for their URB writes, so we introduce virtual
functions emit_urb_write_header() and emit_urb_write_opcode() to take
care of the GS-specific behaviours.
Also, since vertex emission happens at the end of the VS, but in the
middle of the GS, we need to be sure to only call
emit_shader_time_end() during VS vertex emission. We accomplish this
by moving the call to emit_shader_time_end() into the VS
implementation of emit_urb_write_opcode().

In patches that follow, we'll be splitting structs brw_vs_prog_data
and brw_vs_compile into a vec4-generic base struct and a VS-specific
derived struct (this will allow the vec4-generic code to be re-used
for geometry shaders). Having brw_vs_compile point to
brw_vs_prog_data makes it difficult to do this cleanly.
Fortunately most of the functions that use brw_vs_compile (those in
the vec4_visitor class) already have access to brw_vs_prog_data
through a separate pointer (vec4_visitor::prog_data). So all we have
to do is use that pointer consistently, and plumb prog_data through
the few remaining functions that need access to it.
