regex: Unnest nested functions in regcomp.c
This refactor moves four functions out of a nested scope and converts them into static always_inline functions. collseqwc, table_size, symb_table, extra are now initialized to zero because they are passed as function arguments. On x86-64, .text is 16 byte larger likely due to the 4 stores. This is nothing compared to the amount of work that regcomp has to do looking up the collation weights, or other functions. If the non-buildable `sysdeps/generic/dl-machine.h` doesn't count, this patch removes the last `auto inline` usage from glibc.
