add stress test projects

[dsyme]

Add the stress test projects generated by @saul's script in this #2793 (comment)

Having these stress tests available as part of the repo will make it much easier to collaborate on improving performance. They are only 7MB though quite a few files

Example usage:

N=2:
devenv tests\projects\stress\tinsy\shallow\Shallow.sln
devenv tests\projects\stress\tinsy\dense\Dense.sln
devenv tests\projects\stress\tinsy\denseBin\DenseBin.sln

N=4:
devenv tests\projects\stress\tiny\shallow\Shallow.sln
devenv tests\projects\stress\tiny\dense\Dense.sln
devenv tests\projects\stress\tiny\denseBin\DenseBin.sln

N=10:
devenv tests\projects\stress\small\shallow\Shallow.sln
devenv tests\projects\stress\small\dense\Dense.sln
devenv tests\projects\stress\small\denseBin\DenseBin.sln

N=20:
devenv tests\projects\stress\medium\shallow\Shallow.sln
devenv tests\projects\stress\medium\dense\Dense.sln
devenv tests\projects\stress\medium\denseBin\DenseBin.sln

N=30;
devenv tests\projects\stress\big\shallow\Shallow.sln
devenv tests\projects\stress\big\dense\Dense.sln
devenv tests\projects\stress\big\denseBin\DenseBin.sln

N=100:
devenv tests\projects\stress\huge\shallow\Shallow.sln
devenv tests\projects\stress\huge\dense\Dense.sln
devenv tests\projects\stress\huge\denseBin\DenseBin.sln

and the C# equivalents e.g.

devenv tests\projects\stress\huge\shallowCSharp\ShallowCSharp.sln
devenv tests\projects\stress\huge\denseCSharp\DenseCSharp.sln
devenv tests\projects\stress\huge\denseBinCSharp\DenseBinCSharp.sln

For example on "master" today, times are on my laptop

• small\shallow\Shallow.sln (15 projects) - opens after 38sec, 180MB

• big\shallow\Shallow.sln (45 projects) - opens after 1 min of CPU time

• huge\shallow\Shallow.sln (150 projects) - opens after 6 min of CPU time

• small\dense\Dense.sln (10 projects) - opens after 28 sec, 150MB

• big\dense\Dense.sln (30 projects) - does not open, memory grows > 2GB

• huge\dense\Dense.sln (100 projects) - does not open, memory grows > 2GB

( Note: there is no actual code in these projects, each project has an empty list of source files)

Just for the record - the scripts aren't mine, @nickcowle wrote them! 😄
