Commit 45d70806f4386adfb62b0d75949a8aad58e0576f by richard PR42694 Support explicit(bool) in older language modes as an extension. This needs somewhat careful disambiguation, as C++2a explicit(bool) is a breaking change. We only enable it in cases where the source construct could not possibly be anything else.

Commit b54a50f52e9427f250c192a8618b881732e5d7a4 by Jonas Devlieghere [lldb/Reproducers] Extract function for reading environment override (NFC) Create a helper function for reading reproducer overrides from environment variables.

Commit c378e52cb9d1197bd828008ffdeaf3cebdca1506 by arsenm2 Set some fast math attributes in setFunctionAttributes This will provide a more consistent view to codegen for these attributes. The current system is somewhat awkward, and the fields in TargetOptions are reset based on the command line flag if the attribute isn't set. By forcing these attributes with the flag, there can never be an inconsistency in the behavior if code directly inspects the attribute on the function without considering the command line flags.

Commit 066e817b421e8502a72735988e14713940517aaa by Jonas Devlieghere [lldb/Reproducers] Add a flag to always generating a reproducer Add a flag which always generates a reproducer when normally it would be discarded. This is meant for testing purposes to capture a debugger session without modification the session itself.

Commit 8fdafb7dced812b2dc0af77f9668bfe23b4ffb0b by chen3.liu Insert wait instruction after X87 instructions which could raise float-point exception. This patch also modify some mayRaiseFPException flag which set in D68854. Differential Revision: https://reviews.llvm.org/D72750
