The tests are targeting Windows but do not specify an environment. When
executed on Linux, they would use an ELF output rather than the COFF
output. Explicitly provide an environment.

These tests require x86-registered-target, but they don't force the target as
x86 on the command line, which means they will be run and they might fail when
building the x86 backend on another platform (such as AArch64).

Instead of putting the /Yc header into ExtraDeps, give DependencyOutputOptions
a dedicated field for /Yc mode, and let HeaderIncludesCallback hang on to the
full DependencyOutputOptions object, not just ExtraDeps.
Reverts parts of r263352 that are now no longer needed.

Most things even work; see the included FIXMEs for things that need polishing.
Also don't warn about unused flags for the `/Yuh2.h /FIh1.h /FIh2.h`. The
common case is that the pch was built with `/Ych2.h /FIh1.h /FIh2.h`, so h1.h
is in the PCH, and we shouldn't warn about /FIh1.h not having an effect.
(If we wanted to get fancy, we could store the list of -include flags in the
pch and then check that it matches later on.)

-H in gcc mode doesn't print -include headers, but they are included in
depfiles written by MMD and friends. Since /showIncludes is what's used instead
of depfiles, printing /FI there seems important (and matches cl.exe).
Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders
in clang-cl mode and let clang::InitializePreprocessor() not put -include flags
in the <command line> block. This changes the behavior of -E slightly, and it
removes the <command line> flag from the output triggered by setting the
obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these
seem ok to change.

To make this work, delay printing of ExtraDeps in HeaderIncludesCallback a bit,
so that it happens after CompilerInstance::InitializeSourceManager() has run.
General /FI arguments are still missing from /showIncludes output, this still
needs to be fixed.
llvm-svn: 263352
We almost get this right, but not completely (see FIXME). It looks like /FI
headers generally aren't included in /showIncludes yet, but they should be.
But it seems good to have test coverage for the bits that already work.
