Cuong Manh Le 4ad4128d3c cmd/compile: fix bad order of evaluation for min/max builtin
For float or string, min/max builtin performs a runtime call, so we need
to save its result to temporary variable. Otherwise, the runtime call
will clobber closure's arguments currently on the stack when passing
min/max as argument to closures.

Fixes #60990
