Since commit f85913fa08 (VS: Add support for enumerating VS instances
with vswhere, 2022-04-11, v3.24.0-rc1~282^2), if the COM lookup does not
report any VS instances, we fall back to finding vswhere. However, the
`getenv` call returns nullptr if the `ProgramFiles(x86)` environment
variable is not set. Update the logic to tolerate not-set environment
variables. Also check the plain `ProgramFiles` environment variable.
Fixes: #24090
In commit 80f5d28813 (Tutorial: Update step 2 style, 2022-07-25,
v3.25.0-rc1~226^2) we replaced some uses of `USE_MYMATH` with `MY_MATH`.
Restore the former name for consistency with the rest of the tutorial.
Xcode has a separate setting for Swift compile definitions, so we can
compute a dedicated value for it. Therefore we can:
* Support the COMPILE_LANGUAGE generator expression for Swift-specific
filters.
* Avoid passing the `=value` part of definitions, which Swift does
not support.
This revises commit 5cb625eb2f (Xcode: Pass compile definitions to
Swift, 2022-06-19, v3.25.0-rc1~493^2) and reverts commit 12c6fec6b4
(Xcode: Drop CMAKE_INTDIR= definition in Swift targets, 2022-09-30,
v3.25.0-rc1~60^2~2), as the latter is no longer needed.
Fixes: #24086
The C# flag table added by commit 9b06c22648 (VS: Add flag tables for
C#, 2016-12-01, v3.8.0-rc1~230^2) and preserved by commit 6e947179a8
(Add json flag tables for C#, 2018-11-21, v3.14.0-rc1~282^2~27) was
written by hand. Fix the entry name for the `NoStdLib` property.
Fixes: #24077

This was accidentally broken by commit 87c762d435 (CPack: Use
cmCommandLineArgument instead of cmsys::CommandLineArguments,
2022-04-18, v3.24.0-rc1~258^2).
Fixes: #24085
Xcode uses its own heuristics to determine whether or not to accept
top-level code in a source file while Ninja uses the swift driver
heuristics.
With the Swift driver, if the module contains a single file, that file
will be parsed as a top-level code context. With Xcode, the single file
will only be parsed as top-level code if the name of that file is
'main.swift'.
To ensure more consistent behavior between the two generators, if we're
building Swift and the try-compile target type is executable or
undefined, we name the file `main.swift` to ensure that both will handle
the single file as top-level code.
