[PATCH] D51391: [clang-cl,PCH] Add support for #pragma hdrstop

[Mike Rice via Phabricator via cfe-commits]

With clang-cl, when the user specifies /Yc or /Yu without a header
the compiler uses a #pragma hdrstop in the main source file to
determine the end of the PCH.  If a header is specified with /Yc or
/Yu #pragma hdrstop has no effect.

The optional filename argument is not yet supported.
