AsmMacroIoLib.h and AsmMacroIoLibV8.h are used by the CompilerIntrinsicsLib, which is moving to MdePkg. These functions provide standard definitions for ARM/AARCH64 assembly code, respectively, and so are moved to the arch directories in MdePkg to avoid MdePkg having a dependency on ArmPkg. Now that the files are in Arm/ and AArch64/ directories, the filenames are changed to AsmMacroLib.h as we can distinguish the architecture from the path. AsmMacroIoLib.inc is unused and so is removed. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
