regexec: remove alloca usage in build_trtable
It syncs with gnulib version 1731fef3d. On build_trtable prevent inlining, so that it doesn't bloat the caller's stack and use auto variables instead of alloca/malloc. After these changes, build_trtable's total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc's 64 KiB cutoff so there's little point to using alloca to shrink it. Checked on x86_64-linux-gnu.
