[PATCH] D38357: [Support/Regex] Handle tabulators and escaped chars in square brackets.

[Marek Kurdej via Phabricator via cfe-commits]

curdeius created this revision.

This patch is motivated by bug #34739 (https://bugs.llvm.org/show_bug.cgi?id=34739).
Clang-format misbehaves because escape sequence '\t' in regex is treated as literal 't'.
This patch handles escaped characters inside square brackets as well (so that somebody can write `R("^[\[\]\t]")` as a regex pattern).
