Subject: [PATCH 1/3] [Multilib] Custom flags YAML parsing
This patch adds support for custom flags in the multilib YAML file.
Details about this change can be found in:
https://discourse.llvm.org/t/rfc-multilib-custom-flags/81058
CustomFlagDeclaration objects are instantiated using shared_ptr. This is
motivated by the fact that each custom flag value,
CustomFlagValueDetail, contains a back reference to their corresponding
flag declaration.
Since the CustomFlagDeclaration objects are transferred from the YAML
parser to the MultilibSet instance after the parsing is finished, back
references implemented as raw pointers would become dangling. This would
need to be remediated in the copy/move constructors by updating the
pointer.
Therefore it's just simpler and less error-prone to have all references
to CustomFlagDeclaration, including the back reference, as shared_ptr.
This way dangling pointers are not a concern.
