Simon Pilgrim 0238b96c06 [X86] Force fp stack folding tests to keep to specific domain. 
General boolean instructions (AND, ANDN, OR, XOR) need to use a specific domain instruction (and not just the default).

Craig Topper 0271d10d35 [x86] Change u8imm operands to always print as unsigned. This makes shuffle masks and the like make way more sense.

Simon Pilgrim 7e6d573e87 [X86][AVX] Added (V)MOVDDUP / (V)MOVSLDUP / (V)MOVSHDUP memory folding + tests. 
Minor tweak now that D7042 is complete, we can enable stack folding for (V)MOVDDUP and do proper testing.

Added missing AVX ymm folding patterns and fixed alignment for AVX VMOVSLDUP / VMOVSHDUP.

Simon Pilgrim f5dcc1cbe6 [X86][AVX] Simplified diff between AVX1 and SSE42 fp stack folding tests. NFC. 
Changed the AVX1 tests register spill tail call to return a xmm like the SSE42 version - makes doing diffs between them a lot easier without affecting the spills themselves.

Simon Pilgrim 0d68d98bd5 [X86][AVX] Renamed AVX1 fp stack folding tests. NFC. 
The SSE42 version of the AVX1 float stack folding tests will be added shortly, this renames the AVX1 file so that the files will be near each other in a directory listing to help ensure they are kept in sync.
