Nicolai Haehnle	3ffd383a15	AMDGPU: Fix copying i1 value out of loop with non-uniform exit ... Summary: When an i1-value is defined inside of a loop and used outside of it, we cannot simply use the SGPR bitmask from the loop's last iteration. There are also useful and correct cases of an i1-value being copied between basic blocks, e.g. when a condition is computed outside of a loop and used inside it. The concept of dominators is not sufficient to capture what is going on, so I propose the notion of "lane-dominators". Fixes a bug encountered in Nier: Automata.

Artem Tamazov	6edc135d0f	[AMDGPU][llvm-mc] s_getreg/setreg* - hwreg - factor out strings/literals etc. ... Hwreg(...) syntax implementation unified with sendmsg(...). Common strings moved to Utils MathExtras.h functionality utilized. Added missing build dependency in Disassembler.

Nikolay Haustov	6c8c74969a	[AMDGPU] table-driven parser/printer for amd_kernel_code_t structure fields ... This is going to be used in .hsatext disassembler and can be used in current assembler parser (lit tests passed on parsing). Code using this helpers isn't included in this patch. Benefits: unified approach fast field name lookup on parsing Later I would like to enhance some of the field naming/syntax using this code.
