We will now manage the liblzma source tree updates using
the `Utilities/Scripts/update-liblzma.bash` script. Drop
the README that covered the old method.
Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11). The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way. Simply revert it for now.
See issue #16174.

This is important for two reasons:
1. A compiler might warn about a class that has a virtual member
function but no virtual destructor. We don't want to treat the feature
as incomplete in this case.
2. MSVC10 supports the override identifier except on destructors. In
this case, the feature really is incomplete and we want to detect it as
such.
In commit v3.6.0-rc1~174^2 (Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE
for compile rules, 2016-04-06), Ninja learned to look for
`CMAKE_NINJA_FORCE_RESPONSE_FILE` in the current scope or the
environment in order to force response file usage for all compilation
rules.
However, on Windows, the RC compiler goes through cmcldeps which does a
`replace(output, output + ".dep.obj")` on the command line. However,
with a response file (which we name `output + ".rsp"`), the response
file path is replaced instead causing the compiler to (correctly)
complain that the response file `output + ".dep.obj.rsp"` does not
exist.
What needs to happen is for cmcldeps to look through the response file,
replace *its* contents and place it in the `output + ".dep.obj.rsp"`
file.
Also add a test which actually compiles an RC file into a library and
executable for all generators on Windows and additionally test
`CMAKE_NINJA_FORCE_RESPONSE_FILE` for Ninja generators.
Fixes#16167.

5286110d cxx features: add check for override
09aa2c94 Use <unordered_set> where available
ea5477e4 Make C++ feature checks extensible
Run clang-tidy's modernize-use-override checker. This checker must have
issues in version 3.8. It has way too little matches. And it adds
override to destructors. Revert the changes on the destructors and
change override to CM_OVERRIDE.
Turn the feature check for cxx11_unordered_map into a function such that
we can use it for other features as well. Drop the 11 suffix, as we may
want to check features from other standards.
