In the case that __DRI_ATTRIB_FLOAT_BIT is set in the dri config, set
EGL_COLOR_COMPONENT_TYPE_FLOAT_EXT in the egl config. Add a field to the
platform driver visual to indicate if it has components that are in floating
point form.

In order to handle pixel formats that consist of floating point data, enable
floatMode field in the dri config, and set __DRI_ATTRIB_FLOAT_BIT in the
render type attribute.

Change dri2_add_config to take arrays of shifts and sizes, and compare with
those set in the dri config. Convert all platform driver masks
to shifts and sizes.

In order to handle older drivers, where shift attributes aren't available,
we fall back to the mask attributes and compute the shifts with ffs.

bitcount is free from the pipe header dependencies that make u_math.h hard
to include by non-gallium specific code, so move it to bitscan.h. bitscan.h
is included by u_math.h so existing references will continue working.

The existing mask attributes can only support up to 32 bpp. Introduce
per-channel SHIFT attributes that indicate how many bits, from lsb towards
msb, the bit field is offset. A shift of -1 will indicate that there is no
bit field set for the channel.

As old loaders will still be looking for masks, we set the masks to 0 for
any formats wider than 32 bpp.

This debug option allows vkGet[Instance/Device]ProcAddr() to succeed
even if the extension associated with the requested entrypoint was not
enabled.

This has come in handy in a few instances when debugging VR
applications, so I thought it would be good to have a cleaned up version
upstreamed.

A pair of special flags can turn the texture/sampler handle fields into

can be compiled to something like:

This better matches all the other atomic intrinsics such as those for
SSBOs and shared variables where the sign is part of the intrinsic
opcode.  Both generators (GLSL and SPIR-V) know the sign from the type
of the image variable or handle.  In SPIR-V, signed min/max are separate
opcodes from unsigned.
