core: support integer expressions in various commands
For convenience, many commands now accept integer expressions
rather than only simple integers.
These are:
loop, range, incr, string repeat, lrepeat, pack, unpack, rand
This simplifies many cases where previously expr {} or $() was required.
e.g.
foreach i [range 4+1 2*$b] { ... }
string repeat 2**$n a
