#     Pull asm inline support from Miguel Ojeda:
#      "Make use of gcc 9's "asm inline()" (Rasmus Villemoes):
#     
#       gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise
#       crude heuristic that gcc uses to estimate the size of the code
#       represented by an asm() statement. From the gcc docs
#     
#           If you use 'asm inline' instead of just 'asm', then for inlining
#           purposes the size of the asm is taken as the minimum size, ignoring
#           how many instructions GCC thinks it is.
#     
#       For compatibility with older compilers, we obviously want a
#     
#           #if [understands asm inline]
#           #define asm_inline asm inline
#           #else
#           #define asm_inline asm
#           #endif
#     
#       But since we #define the identifier inline to attach some attributes,
#       we have to use an alternate spelling of that keyword. gcc provides
#       both __inline__ and __inline, and we currently #define both to inline,
#       so they all have the same semantics.
#     
#       We have to free up one of __inline__ and __inline, and the latter is
#       by far the easiest.
#     
#       The two x86 changes cause smaller code gen differences than I'd
#       expect, but I think we do want the asm_inline thing available sooner
#       or later, so this is just to get the ball rolling"
