Merge commit a5e1a93ea10f from llvm-project (by Mariya Podchishchaeva): [clang] Fix crash when handling nested immediate invocations Before this patch it was expected that if there was several immediate invocations they all belong to the same expression evaluation context. During parsing of non local variable initializer a new evaluation context is pushed, so code like this ``` namespace scope { struct channel { consteval channel(const char* name) noexcept { } }; consteval const char* make_channel_name(const char* name) { return name;} channel rsx_log(make_channel_name("rsx_log")); } ``` produced a nested immediate invocation whose subexpressions are attached to different expression evaluation contexts. The constructor call belongs to TU context and `make_channel_name` call to context of variable initializer. This patch removes this assumption and adds tracking of previously failed immediate invocations, so it is possible when handling an immediate invocation th check that its subexpressions from possibly another evaluation context contains errors and not produce duplicate diagnostics.
