prologue_end aarch64 tests.

Hi All,

The tests like

llvm/test/DebugInfo/AArch64/prologue_end.ll

llvm/test/DebugInfo/AArch64/ cfi-eof-prologue.ll

Do we see that the above tests are forced with fast-isel ?

anyone from the arm can shed lights the reason for the same ?,

what we see that when we default to global-isel the test cases fails with llvm-10 since it emits the prologue_end like
.loc 1 0 0 prologue_end

but it is not the case with llvm trunk, do this test cases modification (were default to global-isel).

Thank you
