This patch from Le-Chun Wu adds two new shadow warning flags for
C and C++:

  -Wshadow=local which warns if a local variable shadows another local
  variable or parameter,

  -Wshadow=compatible-local which warns if a local variable shadows
  another local variable or parameter whose type is compatible with
  that of the shadowing variable.

It is already on the google/main branch (Google ref 39127) and was
previously submitted by Diego Novillo and reviewed on
http://codereview.appspot.com/4452058

I addressed the review comments and made the following changes:
- Add -Wshadow=global (the default alias for -Wshadow).
- Make the documented options -Wshadow=global, -Wshadow=local
  and -Wshadow=compatible-local (with hidden undocumented aliases
  -Wshadow-local and -Wshadow-compatible-local for compatibility).
- The -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local
  relationships are expressed in common.opt instead of in opts.c
  and documented in invoke.texi.
- The "previous declaration" warnings were turned into notes and use
  the (now) existing infrastructure instead of duplicating the warnings.
  The testcases have been adjusted to expect the notes.
- The conditional change in name-lookup.c for non-locals (where we
  don't want to change the warnings, but just check the global ones)
  has been dropped.
- Use warning_at in c-decl.c (warn_if_shadowing).

    There was a phase ordering issue in the handling of "keyed" array
    literal expressions: the lowering phase was canonicalizing the
    indices/vals before the phase that fixed evaluation order, meaning that
    the evaluation order was incorrect. The fix is to capture the orginal
    ordering and use that ordering when doing traversals (there is already
    something similar being done for struct literal expressions).

This improves a few things in change_zero_ext.  Firstly, it should use
the passed in pattern in recog_for_combine, not the pattern of the insn
(they are not the same if the whole pattern was replaced).  Secondly,
it handled zero_ext of a subreg, but with hard registers we do not get
a subreg, instead the mode of the reg is changed.  So this handles that.
Thirdly, after changing a zero_ext to an AND, the resulting RTL may become
non-canonical, like (ior (ashift ..) (and ..)); the AND should be first,
it is commutative.  And lastly, zero_extract as a set_dest wasn't handled
at all, but now it is.

This fixes the testcase in PR71847, and improves code generation in some
other edge cases too.
