This patch improves the performance of the code generated by the compiler
for attribute Image when applied to user-defined enumeration types and the
sources are compiled with optimizations enabled.
it looks like this is in essence inlining the run-time library routine. In
which case, shouldn't you only do it if inlining is enabled? For example, it
seems rather odd to do this if compiling with -Os.
Best wishes, Duncan.
No test required.

(Expand_Image_Attribute): Enable speed-optimized expansion of
user-defined enumeration types when we are compiling with optimizations
enabled.
