In order to be coherent with the pre-existent API for half floats,
this new API for double is the one meant to be used when doing double
to float conversions. It is no more than a wrapper for the softfloat.h
API but we meant to keep that one private.
v2:
- Fix bug in _mesa_double_to_float_rtz() in the inf/nan detection
using the exponent value.
v3:
- Replace custom f64 -> f32 implementations with the softfloat
one (Andres).
v4:
- Added API usage clarifying comments (Caio).

Implemented fadd, fsub, fmul and ffma for doubles and ffma for floats,
rounding to zero, using a modified implementation from Berkely
Softfloat 3e Library.
Their implementation correctness has been checked with the Berkeley
TestFloat Release 3e tool for x86_64.
v2:
- Reuse util_last_bit64() in _mesa_count_leading_zeros64()
implementation (Connor).
v3:
- Add a specific ffma for floats version (Connor).
- Implement the ffma for doubles version (Andres).
- Lots of fixes in fadd, fsub and fmul (Andres).
- Improved documentation (Andres).
v4:
- Added f64 -> f32 conversion function (Andres).
- Added f32 -> f16 RTZ conversion function (Andres).

Vulkan applications can register with the following structure :
typedef struct VkApplicationInfo {
VkStructureType sType;
const void* pNext;
const char* pApplicationName;
uint32_t applicationVersion;
const char* pEngineName;
uint32_t engineVersion;
uint32_t apiVersion;
} VkApplicationInfo;
This enables the Vulkan implementations to apply workarounds based off
matching this description.
Here we add a new parameter for matching the driconfig options with
the following :
<device driver="anv">
<application engine_name_match="MyOwnEngine.*" engine_versions="10:12,40:42">
<option name="blaaah" value="true" />
