History
Matthew Maurer 4d397d33da Adjust 64-bit ARM data layouts for LLVM update 
LLVM has updated data layouts to specify `Fn32` on 64-bit ARM to avoid
C++ accidentally underaligning functions when trying to comply with
member function ABIs.

This should only affect Rust in cases where we had a similar bug (I
don't believe we have one), but our data layout must match to generate
code.

As a compatibility adaptatation, if LLVM is not version 19 yet, `Fn32`
gets voided from the data layout.
