[PATCH] PR17647: ARM IAS needs Alias for MUL/MLA/SMLAL/UMLAL

[Renato Golin]

Hi,

+def : InstAlias<"mla${s}${p} $Rd, $Rn, $Rm, $Ra",
+            (MLA GPR:$Rd, GPR:$Rn, GPR:$Rm, GPR:$Ra, pred:$p, cc_out:$s)>,
+         Requires<[IsARM, NoV6]>;

R15 can't be used on those as well, would be better to use GPRnopc class.

The rest seems fine, thanks!
