Oliver Smith-Denny 734e71f428 MdePkg: Move AsmMacroIoLib*.h from ArmPkg 
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.

Olivier Martin fb7ea6114a ArmPkg: Ensured the stack is always quad-word aligned 
From the AArch64 Procedure Call Standard (ARM IHI 0055B):

  5.2.2.1 Universal stack constraints
  At all times the following basic constraints must hold:
  - SP mod 16 = 0. The stack must be quad-word aligned.

Olivier Martin b4e53e389d ArmPkg/ArmSmcLib: Fixed SMC helper functions 
The SMC helper functions were buggy as they were assuming that
the values in x1-x7 registers were preserved across an SMC call,
which is not the case.  This patch fixes this issue.

It also simplifies the code by providing only 1 version of the SMC
helper function.  We used to have 4 versions depending on the number
of arguments.  The problem with this approach was that the number of
arguments also dictated the number of return values, which is
completely unrelated.  E.g. you can have an SMC call that takes
1 argument but returns 4 values.
