Jay Foad 13107c2770 [AMDGPU] Add support for GFX11 LDSDIR hazards ...

Detect LDS direct WAR/WAW hazards and compute values for
wait_vdst (va_vdst) parameter.  Where appropriate this
raises wait_vdst from the default 0 to allow concurrent
issue of LDS direct with VALU execution.

Also detect LDS direct versus VMEM source VGPR hazards
and insert vm_vsrc=0 waits using s_waitcnt_depctr.
