[PATCH] D34426: [Driver] Do not increment ActionCount for precompiled headers.

[Manoj Gupta via Phabricator via cfe-commits]

manojgupta created this revision.

If a .h file is specifed as input, it gets compiled to a PCH file.
Handle the PCH Action and do not throw the error:
"cannot specify -o when generating multiple output files"

This fixes PR33533.
