The AOK_SizeDirective part from 5b37c181291210bedfbb7a6af5d51229f3652ef0
(2014-08) seems unneeded nowadays (the root cause has likely been fixed
elsewhere). The part abuses that call dword ptr foo assembles the same way as `call
foo` in Intel syntax, which is going to be fixed (changed) by D149579.
The generated object files for CodeGen/ms-inline-asm-functions.c,
CodeGen/ms-inline-asm-functions.c, and CodeGenCXX/ms-inline-asm-fields.cpp are
unchanged with just this patch.
When D149579 is subsequently applied, the FIXME part of kptr in
CodeGen/ms-inline-asm-functions.c will be fixed.
