* Shared string macros.
*
* Using shared macros helps minimize strings data size because it's easy
* to check if an existing string could be used. String constants don't
* need to be all defined here; defining a string here makes sense if there's
* a high chance the string could be reused. Also, using macros allows
* a call site express the exact string needed, but the macro may map to an
* approximate string to reduce unique string count. Macros can also be
* more easily tuned for low memory targets than #if defined()s throughout
* the code base.
*
* Because format strings behave differently in the call site (they need to
* be followed by format arguments), they use a special prefix DUK_STR_FMT_.
*
* On some compilers using explicit shared strings is preferable; on others
* it may be better to use straight literals because the compiler will combine
* them anyway, and such strings won't end up unnecessarily in a symbol table.

* DUK_OP_BAR_RC 118 // BAR, B=reg, C=const
* DUK_OP_BAR_CC_UNUSED 119 // unused, could be repurposed

* Macro naming is a bit misleading, e.g. "ABC" in macro name but the
