Detailed Description

Assign a GUID to functions as metadata.

GUID calculation takes linkage into account, which may change especially through and after thinlto. By pre-computing and assigning as metadata, this mechanism is resilient to such changes (as well as name changes e.g. suffix ".llvm." additions).
