x86-64: Stack alignment in _dl_tlsdesc_dynamic and red zone usage (bug 31501)
In sysdeps/x86_64/dl-tlsdesc-dynamic.h, the stack pointer is
realigned for some variants (notably _dl_tlsdesc_dynamic_xsavec).
This realignment does not take into account that the function has
already used part of the red zone at this point, thus clobbering
the initally saved register values located there if the stack
alignment inherited from the caller is unfortunate.
