Use .init_array rather than .ctors
LLVM TargetMachines default to using the (now-legacy) .ctors representation of init functions. Mixing .ctors and .init_array representations can cause issues when linking with lld. This happens in practice for: * Our profiling runtime which is currently implicitly built with .init_array since it is built by clang, which sets this field. * External C/C++ code that may be linked into the same process. To support legacy systems which may use .ctors, targets may now specify that they use .ctors via the use_ctors attribute which defaults to false. For debugging and manual control, -Z use-ctors-section=yes/no will allow manual override. Fixes: #71233
