fdd9b09413 tests/tcg/aarch64: Fix compilation parameters for pauth-%
We were incorrectly requiring ARMv8.4 support for the pauth
tests, but Pointer Authentication is an ARMv8.3 extension.
Further, hiding the required architecture within asm() is
not correct.

Correct the architecture version requested, and specify it
in the cflags of the (cross-) compiler rather than in the asm.

d67ebada15 target/arm: Fix output of PAuth Auth
The ARM pseudocode installs the error_code into the original
pointer, not the encrypted pointer.  The difference applies
within the 7 bits of pac data; the result should be the sign
extension of bit 55.

Add a testcase to that effect.
