fe2dfccdf9 Include <alloca.h>.
(access_reg) [HAVE_SYS_UC_ACCESS_H]: Sanitize and simplify this routine.  Turns out
	uc_access(3) works pretty much the way we need it, the only problem is that
	the unwind info for getcontext() seems to be missing as of HP-UX 11.22.
(ia64_uc_access_reg): New function.

f3ca36f42d Fix libunwind enough to be actually useful on HP-UX. tests/bt now prints a very
nice backtrace, handling unwinding across signal handlers just fine.  Main missing
piece right now is that unw_resume() doesn't work because uc_access(3) refuses to
write ar.bsp.  Duh.
