We now identify IBM's Clang-based XL compilers, which define
`__ibmxl__`, as `XLClang` rather than `XL`. In order to support
existing project code that checks for `XL`, add a policy whose OLD
behavior is to present the compiler id as `XL` and whose NEW behavior is
to present the compiler id as `XLClang` as we really detect it.

All uppercase is typically used for command keywords. Non-keyword
arguments should generally be shown as `<something>` according
to the CMake documentation guide.
The original warning pre-dates support for install components.
There are now legitimate scenarios where an install(TARGETS)
command may list a target that is excluded from all, e.g.
hierarchical projects that will never install the component such a
target belongs to.

In commit beb991110d (Remove now-unused code once used on IRIX,
2019-01-11, v3.14.0-rc1~167^2) we removed remnants of IRIX support.
Also remove remnants of MIPSpro compiler support.
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.7 and below to encourage projects to port away
from setting policies to OLD.
Since commit 2e91627dea (ParseImplicitIncludeInfo: add Fortran implicit
include handling, 2019-01-25, v3.14.0-rc1~73^2) we actually populate
`CMAKE_Fortran_IMPLICIT_INCLUDE_DIRECTORIES` for the first time. This
value may be useful to project code to pass to other tooling that wants
to preprocess the way Fortran does, so we should compute the value.
However, compilers like `gfortran` do not actually search their own
implicit include directories for `.mod` files. The directories must be
passed via `-I` in order for `.mod` files in them to be found.
Since Fortran has no standard library header files that we need to avoid
overriding, it is safe to *not* filter out implicit include directories
from those passed explicitly via `-I` options. Skip this filtering so
that include directories specified by project code to find `.mod` files
will be searched by the compiler even if they happen to be implicitly
searched by the preprocessor.

After !2853, the statement that the "longest file extension is
always considered" is no longer true. Both NAME_WLE and
LAST_EXT now return details based on the shortest file
extension.
Fixes: 7a25ef326b (Help: Add documentation for new get_filename_component components, 2019-01-24, 3.14.0-rc1)
In CMake 3.13.x, we had this evaluation for if() conditions:
if(a) elseif(b) else(a) endif(a)
The sensible intention of the change in commit c2efb3efcd (Help: Revise
docs on Scripting Commands, 2018-10-16, v3.14.0-rc1~505^2) was:
> "endif", "endfunction" etc: Explain that the argument is optional and
> maintained for compatibility only
Instead of "endif", it ended up being written to the documentation as
"elseif" by the commit author (oops) to if()'s page.
if(a) elseif(a!?) else() endif(a?)
Truthfully, endif()'s parameter should be an optional verbatim repeat
and not elseif()'s. If it wasn't, elseif() would be described to be the
same as if(). The rightful intended description is:
if(a) elseif(b) else() endif()
Fix that typo.
