erb.rb: Skip creating regexp
if stags and etags are not changed from default.
:putobject insn (of regexp) will be used instead of :toregexp insn.
This means that the regexp won't be compiled for every
`SimpleScanner#scan` call.
It may not be a good idea to apply this kind of optimization for all cases.
But I applied this because it is default scanner and used frequently and has
relatively large impact for benchmark like this:
* Before
app_erb 1.023
* After
app_erb 0.781
This commit fixes only the bottleneck of performance regression introduced
in r53412. For maintainability, I won't fix other small regressions like
additional overhead of method calls.
