[PATCH] wined3d: Use intBitsToFloat() instead of uintBitsToFloat().

[Paul Gofman]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=47039

There is no uint type in GLSL version < 1.3, while ARB_shader_bit_encoding
may still be supported.

(wined3d: Check GLSL version when using ARB_shader_bit_encoding with uvec4).
