Fix renaming of bs_put_string instructions
The clause was formerly commented-out because at this point in the code,
no bs_put_string instruction has been generated yet when compiling from
Erlang.
If an Erlang module is compiled to BEAM assembly and the result contains
a bs_put_string instruction, the output can't be compiled to binary
anymore and the compiler crashes with the following error:
$ erlc prs.S
Function: compress/1
prs.S:none: internal error in beam_block;
crash reason: {{case_clause,
{'EXIT',
{function_clause,
[{beam_utils,live_opt,
