When instructions are deleted, they leave tombstone SlotIndex entries.
The isZeroLength method should ignore these null indexes.

This causes RABasic to sometimes spill a callee-saved register in the
abi-isel.ll test, so don't run that test with -regalloc=basic.  Prioritizing
register allocation according to spill weight can cause more registers to be
used.

Fix bad test case; not all compilers are guaranteed to step into code inlined from the STL header file.

unambiguous iteration support.  So that we could, for example:

    ...

    REGs = lldbutil.get_GPRs(frame)
    print "Number of general purpose registers: %d" % len(REGs)
    for reg in REGs:
        print "%s => %s" %(reg.GetName(), reg.GetValue())

Preserve the original triple in the NetBSD toolchain when using -m32 or
-m64 and the resulting effective target is different from the triple it
started with. This allows -m32 to use the same assembler/linking in
cross-compiling mode and avoids confusion about passing down target
specific flags in that case like --32.
