[llvm] [llvm][CAS] Remove unused functions (PR #168856)

[David Spickett via llvm-commits]

https://github.com/DavidSpickett created https://github.com/llvm/llvm-project/pull/168856

Building with GCC I got:
```
<...>/OnDiskGraphDB.cpp:624:18: warning: ‘static {anonymous}::DataRecordHandle {anonymous}::DataRecordHandle::construct(char*, const {anonymous}::DataRecordHandle::Input&)’ defined but not used [-Wunused-function]
  624 | DataRecordHandle DataRecordHandle::construct(char *Mem, const Input &I) {
      |                  ^~~~~~~~~~~~~~~~
<...>/OnDiskGraphDB.cpp:456:1: warning: ‘static {anonymous}::DataRecordHandle {anonymous}::DataRecordHandle::create(llvm::function_ref<char*(long unsigned int)>, const {anonymous}::DataRecordHandle::Input&)’ defined but not used [-Wunused-function]
  456 | DataRecordHandle::create(function_ref<char *(size_t Size)> Alloc,
      | ^~~~~~~~~~~~~~~~
```

These implement parts of a class that is defined in an anonymous namespace. All llvm tests passed with them removed.
