pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr
node directly. Currently, this only affects pseudo-destructor
expressions when they are parsed, but not after template
instantiation. That's coming next...

Improve parsing of pseudo-destructor-names. When parsing the
nested-name-specifier and we hit the sequence of tokens X :: ~, query
the actual module to determine whether X is a type-name (in which case
the X :: is part of the pseudo-destructor-name but not the
nested-name-specifier) or not (in which case the X :: is part of the
nested-name-specifier).

Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo
class to support the Clang MicroBlaze target.

Additionally, minor fixes which remove some unused PIC code 
(PIC is not supported yet in the MicroBlaze backend) and
removed some unused variables.

destructor calls, e.g., 

  p->T::~T

We now detect when the member access that we've parsed, e.g.,

  p-> or x.

may be a pseudo-destructor expression, either because the type of p or
x is a scalar or because it is dependent (and, therefore, may become a
scalar at template instantiation time). 

We then parse the pseudo-destructor grammar specifically:

  ::[opt] nested-name-specifier[opt] type-name :: ∼ type-name

and hand those results to a new action, ActOnPseudoDestructorExpr,
which will cope with both dependent member accesses of destructors and
with pseudo-destructor expressions.

This commit affects the parsing of pseudo-destructors, only; the
semantic actions still go through the semantic actions for member
access expressions. That will change soon.

a common source of oddities and, in theory, removes some redundant ABI
computations.  Also fixes a miscompile I introduced yesterday by refactoring
some code and causing a slightly different code path to be taken that
didn't perform *parameter* type canonicalization, just normal type
canonicalization;  this in turn caused a bit of ABI code to misfire because
it was looking for 'double' or 'float' but received 'const float'.

Also add an easy macro at the top of DAGISelEmitter.cpp to enable
it.  Lets see if I can avoid accidentally turning it on :)

necessary to swap the operands to handle NaN and negative zero properly.

Also, reintroduce logic for checking for NaN conditions when forming
SSE min and max instructions, fixed to take into consideration NaNs and
negative zeros. This allows forming min and max instructions in more
cases.

to adding them in a determinstic order (bottom up from 
the root) based on the structure of the graph itself.

This updates tests for some random changes, interesting
bits: CodeGen/Blackfin/promote-logic.ll no longer crashes.
I have no idea why, but that's good right?

CodeGen/X86/2009-07-16-LoadFoldingBug.ll also fails, but
now compiles to have one fewer constant pool entry, making
the expected load that was being folded disappear.  Since it
is an unreduced mass of gnast, I just removed it.

This fixes PR6370
