anv/pipeline: Be smarter about depth/stencil state

It's a bit hard to measure because it almost gets lost in the noise,
but this seemed to help Dota 2 by a percent or two on my Broadwell
GT3e desktop.

anv: Add support for the PMA fix on Broadwell

This helps Dota 2 on Broadwell by 8-9%.  I also hacked up the driver and
used the Sascha "shadowmapping" demo to get some results.  Setting
uses_kill to true dropped the framerate on the demo by 25-30%.  Enabling
the PMA fix brought it back up to around 90% of the original framerate.

anv: Disable stencil writes when both write masks are zero

Vulkan doesn't have a stencilWriteEnable bit like it does for depth.
Instead, you have a stencil mask.  Since the stencil mask is handled as
dynamic state, we have to handle it later during command buffer
construction.  This, combined with a later commit, seems to help Dota2
on my Broadwell GT3e desktop by a couple percent because it allows the
hardware to move the depth and stencil writes to early in more cases.

anv: Add support for shaderStorageImageWriteWithoutFormat

This allows shaders to write to storage images declared with unknown
format if they are decorated with NonReadable ("writeonly" in GLSL).

Previously an image view would always use a lowered format for its
surface state, however when a shader declares a write-only image, we
should use the real format. Since we don't know at view creation time
whether it will be used with only write-only images in shaders, create
two surface states using both the original format and the lowered
format. When emitting the binding table, choose between the states
based on whether the image is declared write-only in the shader.

Tested on both Sascha Willems' computeshader sample (with the original
shaders and ones modified to declare images writeonly and omit their
format qualifiers) and on our own shaders for which we need support
for this.

configure.ac: Drop LLVM compiler flags more radically

Drop all -m*, -W*, -O*, -g* and -f* flags, with the exception of
-fno-rtti, which must be used if it's part of the llvm-config --cxxflags
output. We don't want LLVM to dictate the flags we use, and it can even
cause build failures, e.g. if LLVM and Mesa are built with different
compilers.

While we're at it, eat any whitespace preceding dropped flags as well.

glsl: non-last member unsized array on SSBO must fail compilation on GLSL ES 3.1

From GLSL ES 3.10 spec, section 4.1.9 "Arrays":

"If an array is declared as the last member of a shader storage block
 and the size is not specified at compile-time, it is sized at run-time.
 In all other cases, arrays are sized only at compile-time."

In desktop GLSL it is allowed to have unsized-arrays that are
not last, as long as we can determine that they are implicitly
sized, which is detected at link-time.
