handle arbitrary precision integers and any number
of parts.  For example, on a 32 bit machine an i50
corresponds to two i32 parts.  getCopyToParts will
extend the i50 to an i64 then write half of the i64
to each part; getCopyFromParts will combine the two
i32 parts into an i64 then truncate the result to
i50.

Reordered some cases in the switch statement of GRConstant::Visit() so
that they are ordered alphabetically based on AST node type.

Modified "ProcessBranch" in GRConstants to prune branches with symbolic

variable (with step 1) and m is its final value. Then, the correct trip 
count is SMAX(m,n)-n. Previously, we used SMAX(0,m-n), but m-n may 
overflow and can't in general be interpreted as signed.

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.

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.
