[llvm] [ORC] Mangle SimpleNativeMemoryMap CI names as C (PR #225074)

[Lang Hames via llvm-commits]

https://github.com/lhames created https://github.com/llvm/llvm-project/pull/225074

Flip the SimpleNativeMemoryMap memory-manager descriptors (instance + reserve/initialize/deinitialize/release) from Verbatim to C, so their names carry the target's C mangling. The controller and in-tree executor mangle the same specs, and no other provider defines these names, so they stay in sync; nothing else defines these names.

Also update the CreateFromExecutionSession test to use the process triple so that its name mangling matches the target mangling above.

Subject: [PATCH] [ORC] Mangle SimpleNativeMemoryMap CI names as C

Flip the SimpleNativeMemoryMap memory-manager descriptors (instance +
reserve/initialize/deinitialize/release) from Verbatim to C, so their
names carry the target's C mangling. The controller and in-tree executor
mangle the same specs, and no other provider defines these names, so
they stay in sync; nothing else defines these names.

Also update the CreateFromExecutionSession test to use the process
triple so that its name mangling matches the target mangling above.
