Allow the parser to detect invalid DeclSpec's. This fixes http://llvm.org/bugs/show_bug.cgi?id=1987.

This commit only "guards" the call to ParseDeclarationSpecifiers() in ParseDeclarationOrFunctionDefinition(). 

We could consider guarding all calls, however this is a bit radical (since it effectively stops parsing the declaration once we have a bad declspec). Will discuss with Chris tomorrow.

Several cleanups surrounding Parser::ParseAsmStatement() and Parser::FuzzyParseMicrosoftAsmStatement().

Fixed a horrible bug in lval:DeclVar::classof(RValue* V); we weren't checking
V was an LValue, allowing nonlval::ConcereteInts to match isa<lval::DeclVar>.

BumpPtrAllocator argument to their constructors.  This BumpPtrAllocator
will be used to allocate trees.  If no BumpPtrAllocator is provided, one
is created (as before).

Move policy on unnamed fields (a Microsoft extension) from Parser::ParseStructDeclaration() to the driver.

llvm-svn: 46974

Move Microsoft __declspec hack from the parser to the preprocessor. Since we have no plans to actually implement this construct, it is cleaner to limit the change to the preprocessor.

After yesterday's discussion (http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-February/001044.html), decided not to change the semantics of Type::isIncompleteType(). 

This commit simply changes a couple comments to reflect this decision.

to the RHS. This simple change allows to compute loop iteration count 
for loops with condition similar to the one in the testcase (which seems 
to be quite common).

Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().

Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.

getNumRegisters.  This is needed for calling functions
with apint parameters or return values.

arbitrary iteration.

The patch:
1) changes SCEVSDivExpr into SCEVUDivExpr,
2) replaces PartialFact() function with BinomialCoefficient(); the 
computations (essentially, the division) in BinomialCoefficient() are 
performed with the apprioprate bitwidth necessary to avoid overflow; 
unsigned division is used instead of the signed one.

Computations in BinomialCoefficient() require support from the code 
generator for APInts. Currently, we use a hack rounding up the 
neccessary bitwidth to the nearest power of 2. The hack is easy to turn 
off in future.

One remaining issue: we assume the divisor of the binomial coefficient 
formula can be computed accurately using 16 bits. It means we can handle 
AddRecs of length up to 9. In future, we should use APInts to evaluate 
the divisor.

Thanks to Nicholas for cooperation!
