* Reduce code bloat in arginfo by using specialised string releases
Comparing this patch to master (c7da728574),
with a plain configure command without any options:
```
text data bss dec hex filename
20683738 1592400 137712 22413850 156021a sapi/cli/php
20688522 1592400 137712 22418634 15614ca sapi/cli/php_old
```
We see a minor reduction of 0.023% in code size.
* Also use true for the other initialization line
* Also use specialized code for consts
