[expr] currently generates quite a bit of code for something like:

expr 1*2*3*4*5

Since all of those operators are constant, it should be possible to  
have that expr call be distilled to:

.sub foo :anon
   $P0 = new TclInt
   $P0 = 120
   .return($P0)
.end


Should probably convert [expr] to be inlined before implementing this.
