From today's testing, I got two regressions.
        ecma_3/Date/15.9.5.4.js
        ecma_3/Function/regress-58274.js

2 regressions found.
0 tests fixed.

  The string access is not correct, if I access from the beginning a[0], a[1], a[2], ....

Ex 1:
# ./jsc
> a="01"
01
> a[0]
0
> a[1]
0 <--- THIS IS WRONG!
> a[2]
undefined

Ex 2:
# ./jsc
> a="01"
01
> a[2]
undefined
> a[1]
1 <--- THIS IS CORRECT!
> a[0]
0

  Can anyone help?  Maybe something is wrong in emitSlow_op_get_by_val.
Thanks a lot!

Chao-ying
