any alternative targets at this point other than "darwin," so we now default to
Darwin targets (for now).

not needed, and it was never extensively tested.  If we need an intrusive
reference-counting smart pointer, we can always import intrusive_ptr from
boost.

define float @test_extract_elt(<1 x float> * %P) {
	%p = load <1 x float>* %P
	%R = extractelement <1 x float> %p, i32 0
	ret float %R

we default to "i386-apple-darwin".  This is an interim solution.

Removed processing of "linux" triples from Targets.cpp, since we don't have
any sensical Linux target support (yet).

Cleaned up error processing of targets; added better diagnostics.

Removed debugging fprintfs for printing targets.
Implemented error messages when processing invalid targets.

replaces the functionality previously provided by just "-arch" (which is still
supported but has different semantics).

The new behavior is as follows:

(1) If the user does not specify -triple:

   (a) If no -arch options are specified, the target triple used is the host
   triple (in llvm/Config/config.h).
   
   (b) If one or more -arch's are specified (and no -triple), then there is
       one triple for each -arch, where the specified arch is substituted
       for the arch in the host triple.  Example:
          host triple = i686-apple-darwin9
          command: clang  -arch ppc -arch ppc64 ...
          triples used: ppc-apple-darwin9  ppc64-apple-darwin9
          
(2) The user does specify a -triple (only one allowed):

  (a) If no -arch options are specified, the triple specified by -triple
      is used.  E.g clang -triple i686-apple-darwin9
      
  (b) If one or more -arch options are specified, then the triple specified
      by -triple is used as the primary target, and the arch's specified
      by -arch are used to create secondary targets.  For example:
      
      clang -triple i686-apple-darwin9 -arch ppc -arch ppc64
      
      has the following targets:
         i686-apple-darwin9  (primary target)
         ppc-apple-darwin9
         ppc64-apple-darwin9


Other changes related to the changes to the driver:

- TargetInfoImpl now includes the triple string.

- TargetInfo::getTargetTriple returns the triple for its primary target.

- test case test/Parser/portability.c has been updated because "-arch linux" is
  no longer valid ("linux" is an OS, not an arch); instead we use a bogus
  architecture "bogusW16W16" where WCharWidth=16 and WCharAlign=16.

attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

provide handy accessors to the subexpressions of ConditionalOperator that
automatically take into account the GCC extension where the "LHS" expression is
omitted: e.g x ?: y;. When the LHS expression is available, getTrueExpr() is the
same as getLHS(); when LHS is NULL, getTrueExpr() returns the condition expression.
