Merging r325139:
------------------------------------------------------------------------
r325139 | rafael | 2018-02-14 17:34:27 +0100 (Wed, 14 Feb 2018) | 12 lines
Store defined macros in MCContext.
So that macros defined in inline assembly blocks are available to the
whole file.
This provides a consistent behavior with other assembly directives,
since equations for example are already preserved between inline
assembly blocks.
PR: 36110
Patch by Roger!
