[Mesa-stable] [Review Request (master branch)] compiler: change datatype of 'spacing' in shader_info with uint_8

[Neha Bhende]

With msvc compiler, enum is signed int. It caused failures with
piglit test and glretrace gl4_arb_tessellation_shader_v1

Fixes 84a1a2578dab ('compiler: pack shader_info from 160 bytes to 96 bytes')

Fixes vmware bug 2480550
