Backport of #92123 to release/8.0
Customer Impact
The JIT may crash the process during startup in custom hosting scenarios where
stdoutis closed before the JIT is initialized. Customer reported in #91856.Testing
Manually verified that the JIT code making I/O operations on stdout no longer runs (unless needed, e.g. due to
DOTNET_JitDisasmbeing set).Risk
Low, make some code not run during startup/shutdown, and make some mechanical changes in code that does not run in release builds.
