Builtin function. The function expects an identifier as argument in braces.
The argument is evaluated, and the function yields "true" if the identifier
is defined as an instruction mnemonic that is recognized by the assembler.
Example:
The argument is evaluated, and the function yields "true" if the identifier
has already been defined as the name of a macro. Otherwise the function yields
false. Example:
<tscreen><verb>
.if .not .ismnemonic(ina)
.macro ina

.endif
.macro add foo

adc foo
