4e50062028 radeonsi: pass tessellation ring addresses via user SGPRs 
This removes s_load_dword latency for tess rings.

We need just 1 SGPR for the address if we use 64K alignment. The final asm
for recreating the descriptor is:

    // s2 is (address >> 16)
    s_mov_b32 s3, 0
    s_lshl_b64 s[4:5], s[2:3], 16
    s_mov_b32 s6, -1
    s_mov_b32 s7, 0x27fac

v2: bitcast the descriptor type from v2i64 to v4i32

9fd9a7d0ba radeonsi: remove VS epilog code, compile VS with PrimID export on demand 
The use of PrimID in the pixel shader is too rare to deserve such
a sizable support code.

The initial idea of the VS epilog was to move the clipping code there and
remove it based on states, but optimized variants are now used to do that
and are easier to support, so the VS epilog has turned out to be not so
useful.
