scripts: get_abi.pl: precompile what match regexes
In order to earn some time during matches, pre-compile regexes.
Before this patch:
$ time ./scripts/get_abi.pl undefined |wc -l
6970
real 0m54,751s
user 0m54,022s
sys 0m0,592s
Afterwards:
$ time ./scripts/get_abi.pl undefined |wc -l
6970
real 0m5,888s
user 0m5,310s
sys 0m0,562s
