[PATCH] D143142: [clang][lex] Enable Lexer to grow its buffer

[Vassil Vassilev via Phabricator via cfe-commits]

v.g.vassilev added a comment.

We should probably add some tests here. Alternatively we can add the tests from https://reviews.llvm.org/D143148 but that'd make this patch bulkier and probably harder to review.
