  A series of Clang-related powerpc commits

  r310146:
    Use the right bitwise OR operation for clearing single-step at trap time.
  r311912:
    Force all TOC references in asm to include '@toc'
  r312369:
    Use the explicit expanded form of cmp.
  r312617:
    Hide the 'MOREARGS' macro, it conflicts with contrib code, and is only used
    in one file.
  r312614:
    Don't pass -Wa,-many through clang, the integrated as doesn't support it.
  r312659:
    Avoid using non-zero argument for __builtin_frame_address().
  r312974:
    Add a INTR_TRIG_INVALID, and use it in the powerpc interrupt code.
  r312977:
    Force the setting of bit 7 in the sysmouse packet byte 1 to be unsigned.
  r313005:
    Update CFLAGS for clang compatibility
  r314826:
    Clang in base now supports -mlongcall, so remove this hack

sys: use our roundup2/rounddown2() macros when param.h is available.

2016-04-21T19:57:40+00:00

rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.

This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.

sys/dev: use our nitems() macro when it is avaliable through param.h.

No functional change, only trivial cases are done in this sweep,
Drivers that can get further enhancements will be done independently.
