aa29b98f1d Check for dl_phdr_removals_counter. 
Check whether compiler supports -static-libcxa option (needed when
building the shared objects with the Intel 8.x compiler).
(LDFLAGS_STATIC_LIBCXA): Substitute its value.

(validate_cache): If HAVE_DL_PHDR_REMOVALS_COUNTER is defined, use
	dl_phdr_removals_counter() to validate the cache.  This is
	much more efficient than using dl_iterate_phdr(), since it
	avoids locking.

7e8488d45d Allow unw_get_proc_name() to be called from signal-handler (for 
cursors in the local address-space).
Clarify that unw_get_proc_info(), unw_get_proc_info_by_ip(),
unw_init_remote(), unw_resume(), and unw_step() are async-signal
safe only from the local address-space (we can't make any guarantees
beyond that because of the dependency of the per-address-space
callback routines, which may have all kinds of restrictions).

77f159fe41 linux: Reimplement maps_init()/maps_next()/maps_close() such that

	Warm up the TLB before measuring the cold-cache cases.

	Write to "big" to ensure it's backed by real memory
	(not just by the zero page).
