`*-windows-msvc` on non cl driver modes (#109607)
Similar to previous PRs I've done to change some `IsCLMode` checks to
`isWindowsMSVCEnvironment`.
I stumbled into this one accidentally last week. I did some greps and I
think this is the last one for now. All the remaining `IsCLMode` checks
are only valid for the cl driver mode.
For the `*-windows-msvc` target MSVC link.exe and lld are supported. LTO
isn't supported with MSVC link.exe and so we error when lto is enabled
but MSVC link.exe is being used. However we only error if the driver
mode is cl.
If we are using the clang driver with the `*-windows-msvc` target then
ensure an error is also emitted when LTO and MSVC link.exe are used
together.

This reverts commit 4817b7729a1846b709ec02b98bfe11b0125f8e8f.
It caused some `^/\n` and had some objection about its readability improvement.

The convention does not add //\n. Having all RUN/CHECK lines separated by //\n
makes editor movement difficult (e.g. { } in Vim).

LLVMgold.so tests are duplicated in several places. Deduplicate them.
Move the tests to lto.c and lto.cu
Specify -fuse-ld=bfd or -fuse-ld=gold.
In a future change, if -fuse-ld=lld or CLANG_DEFAULT_LINKER=lld without -fuse-ld=, we will remove -plugin /path/to/LLVMgold.so

With tests fixed for Windows style paths now that they are going
through path canonicalization.

Summary:
Relanding https://reviews.llvm.org/D35739 which was reverted because
it broke the tests on non-Linux. The tests have been fixed to be
platform agnostic, and additional tests have been added to make sure
that the plugin has the correct extension on each platform
(%pluginext doesn't work in CHECK lines).

This recommits r250398 with fixes to the tests for bot failures.
Add "-target x86_64-unknown-linux" to the clang invocations that
check for the gold plugin.

Rolling this back for now since there are a couple of bot failures on
the new tests I added, and I won't have a chance to look at them in detail
until later this afternoon. I think the new tests need some restrictions on
having the gold plugin available.
This reverts commit r250398.

Summary:
Add clang support for -flto=thin option, which is used to set the
EmitFunctionSummary code gen option on compiles.
Add -flto=full as an alias to the existing -flto.
Add tests to check for proper overriding of -flto variants on the
command line, and convert grep tests to FileCheck.
