Subject: Add support for testing via ILLINK
X-Git-Tag: submit/tizen/20210909.063632~11030^2~7725
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0a75623de343f383f132e17d9c7f6c4d766f43e8;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Add support for testing via ILLINK

Add support for testing via ILLINK

This commit has the following changes:
1) Setup the testing infrastructure to run the CoreCLR tests after linking through ILLinker
    `runtest.cmd /link <path-to-illink.exe>`
2) The linker is taken as an argument for runtest.cmd, typically the corebuild of
    https://github.com/mono/linker
3) Tests are run by linking the test binaries and all libraries except `System.Private.Corelib.dll`
4) For tests that use reflection, setup Reflection roots in source directories as `<test>.reflect.xml`
