[JSC] Remove redundant to_string in single-expression template literals
https://bugs.webkit.org/show_bug.cgi?id=308693
Reviewed by Yusuke Suzuki.
`${expr}` emits two consecutive to_string opcodes because
the loop body (L339) already calls emitToString on the expression,
and the size()==1 fast path (L350) calls emitToString again.
Before:
[0] enter
[1] mov loc5, arg1
[4] to_string loc5, loc5
[7] to_string loc5, loc5 <- redundant
[10] ret loc5
After:
[0] enter
[1] mov loc5, arg1
[4] to_string loc5, loc5
[7] ret loc5
