Bug 1537641 - Make MIDL use clang-cl as a preprocessor. r=dmajor Using clang-cl as a preprocessor fails with: ``` In file included from z:\build\build\src\accessible\ipc\win\handler\HandlerData.idl:8: z:\build\build\src\accessible\ipc\win\handler/AccessibleHandler.h(27,8): error: pasting formed 'Accessible2_3.', an invalid preprocessing token [-Winvalid-token-paste] import NEWEST_IA2_IDL; ^ z:\build\build\src\accessible\ipc\win\handler/AccessibleHandler.h(15,24): note: expanded from macro 'NEWEST_IA2_IDL' ^ z:\build\build\src\accessible\ipc\win\handler/AccessibleHandler.h(14,22): note: expanded from macro 'IDLFOR' ^ z:\build\build\src\accessible\ipc\win\handler/AccessibleHandler.h(13,36): note: expanded from macro '__GENIDL' ^ 1 error generated. midl : command line error MIDL1003 : error returned by the C preprocessor (1) ``` There's only one place using the NEWEST_IA2_IDL and accompanying macros, we can just avoid the issue altogether by expanding it manually (and it's not like the macro buys much, the other arm of the __midl ifdef has a #include "Accessible2_3.h" that doesn't use the macro either, presumably for the same reason).
