This patch adds H- and L-variants of StringCharCodeAt and StringLength. StringCharCodeAt is used to inline a constant function call of String.prototype.charCodeAt and to implement the corresponding inline runtime function. It does not yet use the recently introduced extra IC state. (We can specialize on string encoding and avoid deopts because of out of bounds accesses.) StringLength needs more work because the stub version of it also supports strings wrappers and it matters in some cases. (We have to separate the string only case.)
