1031e5d9 FindMatlab: add verbosity to the nightly tests

Just to make it easier to find places where containers are cleared in
order to be recomputed.

It will be destroyed anyway.  This also makes it easier to search for
places where containers are atually cleared in order to be recomputed.

The `ARGC`/`ARGV#` variables in function scope hold the original
arguments with no ;-list flattening.  Add a way for functions to
cleanly parse arguments that may contain `;`.  This also avoids
extra copying of the arguments.

Richard W.M. Jones (1):
      12f000d5 abi.h: Add RISC-V, a little-endian architecture.

Teach the lexer to match and return specific Fortran keywords as tokens.
Update the parser to use these instead of always using a WORD token and
then checking the text.  This avoids extra string comparisons and will
allow more grammar productions to be unambiguously added later for
additional Fortran statements.

Our Fortran grammar is a bare minimum to extract dependencies.
Other statement syntax can be ignored, so simply skip to the
end of unrecognized statements.  This allows some of our existing
productions to be dropped.

290e4ce8 install: Fix computed import prefix in export files when it is "/"

f9973166 ExternalData: Tolerate files duplicated across multiple targets

Call the generator "Visual Studio 15" without any year because the
preview version of VS 15 does not provide a year in the product name.

Copy cmGlobalVisualStudio14Generator to cmGlobalVisualStudio15Generator
and update version numbers accordingly.  Add the VS15 enumeration value.
Note that we do not need to add a MSVC15 variable or v150 toolset
because Visual Studio 15 comes with an updated version of the v140
toolset and remains ABI-compatible.

Teach tests VSExternalInclude, RunCMake.GeneratorPlatform, and
RunCMake.GeneratorToolset to treat VS 15 as they do VS 10-14.

Closes: #16143

If multiple ExternalData_Target_Add calls generate the same output file
then we need to avoid calling add_custom_command multiple times with
that output.  This was already done within a single target by setting a
variable in the local function scope.  This will not be visible in other
calls though so we need to use a directory property instead to prevent
adding a custom command multiple times for one output in a directory.

Normally it is not safe to have multiple custom commands that produce
the same output file across multiple independent targets, but since we
use atomic replacement of outputs the resulting races should not be a
problem.  For the convenience of projects, tolerate this instead of
diagnosing it.  In particular, we previously allowed up to two copies
of the custom command in one directory because CMake has a fallback
from MAIN_DEPENDENCY to an `<output>.rule` file.

While at it, add a note to the documentation that typically only one
external data target should be needed for a project.
