    • D3D11: Implement a dirty bit for Shaders. · c8bee335
      Jamie Madill authored 
      This allows us to skip calling the dynamic shader generation and
program shader application when there haven't been any state
changes. It builds on the previous work that immediately update
state caches in the VertexArray11 and Framebuffer11. It should
improve performance in draw-call limited applications by a small
margin.

For reference, here are the conditions under which the shaders
are refreshed:

1. Directly changing the program executable
2. The vertex attribute layout
3. The fragment shader's rendertargets
4. Enabling/disabling rasterizer discard
5. Enabling/disabling transform feedback
6. An internal shader was used
7. Drawing with/without point sprites

Improves the score of the draw call stress test for the D3D11
back-end (with null driver) by about 40% on my test machine.

The 9_3 back-end seems to have an issue where the getSRV call
to a texture storage can change the "use level zero workaround"
status of the storage, which in turn will invalidate the state.
Since this is localized to 9_3 only, put in a hack to disable
an assert check for now.

    • Removed "name" and "used" from variable location. · fb997ec1
      Jamie Madill authored 
      The used flag was redundant with the index (which used MAXUINT). The
name was redundant with the stored uniform. Removing these gives a
very minor performance speed up when iterating and retrieving
uniform locations.

    • D3D11: Fix ClearBufferiv with STENCIL. · 805d281a
      Jamie Madill authored 
      For some reason we were using the second GLint value passed into the
method, when the spec says we should have a single clear value.

Noticed when adding tests for lazy robust resource init (tests will
be added in a subsequent patch).

    • Pass Context to Framebuffer11 dirty callback. · ea84f6ff
      Jamie Madill authored 
      This allows us to call StateManager11::invalidateRenderTarget from the
Framebuffer11::signal function, which will then trigger state refresh
on the next draw call.

This requires passing Context through a few more Renderbuffer methods,
and reorganizing the RenderTarget signalling so that it doesn't signal
dirty in the destructor. Instead they are signaled as they are
destroyed in the containing classes.
