Allow region-length to be negative in dynamic region info. This is used to
for describing fixed epilogues and makes it possible to share region descriptors
for such epilogues, regardless of the size of a procedure.
Start working on a dynamic unwind-info tester.

Clarify man-page for unw_resume().
For the test-cases where this makes sense, test both local-only and
generic cases.

Lia64-test-rbs.
(TESTS_cdep): Replace test-exc, test-resume-sig, and test-dyn1 with
G (generic) and L (local-only) variants.
(Lia64_test_rbs_SOURCES): Rename from ia64_test_rbs_SOURCES.
(Gia64_test_rbs_SOURCES): New macro.
(Lia64_test_stack_SOURCES): Rename from ia64_test_stack_SOURCES.
(Gia64_test_stack_SOURCES): New macro.

or not a given address is part of a register-backing store. This test is implemented
by rbs_contains().
Fix and greatly simplify ia64 rbs-switching code. ia64-test-rbs now passes
100,000 iterations of random testing.
BKrev: 3e55d6farvnB-gMiDPTFoO1XVBzEtA
(run_check): Limit unwind_count to range 1..(nfuncs+RECURSION_DEPTH).
Fix off-by-one but that counter-acted a bug in ia64-test-rbs-asm.S.
(Logical change 1.52)
we now switch to the new backing-store immediately.
(rbs_underflow): Remove.
(rbs_find_stacked): No longer assume that c->bsp is contained in the current
rbs. If it is not, first find the backing-store that's backing c->bsp.
(rbs_cover_and_flush): Use rbs_contains() instead of (broken) open code.
Handle the case where the initial bsp points to an RNaT slot.

Fix unw_resume() some more. Getting there, slowly. tests/ia64-test-rbs doesn't
pass fully yet, but it's getting quite far already.

(NELEMS): New macro.
(RECURSION_DEPTH): Fix definition: loadup() allocates 93 local regs, not 95.
(spill_func_t): Make it return an "int".
(DCL): Adjust accordingly.
(verbose): New variable.
(nerrors): Make it an "int".
(unwind_count): Ditto.
(unwind_and_resume): Make it return an int. Print info-output only if verbose is
set. After unwinding to the desired point, redirect IP to
resumption_point_label and store return value in EH_ARG0 and original
IP in EH_ARG1.
(run_check): New function.
(main): Remove open test code and call run_check() instead.

to original backing store.
(LD_LOC): Load only 4 bytes, not 8 bytes.
(CK_LOC): New macro.
(loadup): ar.pfs is saved in r36, not r34. After returning from subroutine call,
check local variables to make sure they still contain the correct values.
(resumption_point): New function.
