For now, don't split live intervals around x87 stack register barriers. FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them.

LargeBlockInfo, we can now dramatically simplify their implementation
and speed them up at the same time.  Now the code has time proportional
to the number of uses of the alloca, not the size of the block.

This also eliminates code that tried to batch up different allocas which
are used in the same blocks, and eliminates the 'retry list' logic which
was baroque and no unneccesary.  In addition to being a speedup for crazy
cases, this is also a nice cleanup:

a trivial dense map.  Use this in RewriteSingleStoreAlloca to
avoid aggressively rescanning blocks over and over again.  This
fixes PR2925, speeding up mem2reg on the testcase in that bug
from 4.56s to 0.02s in a debug build on my machine.

1. It introduces new parser level abstractions for designators
   that are used to communicate between parser and sema.
2. This fixes a FIXME where "identifier ':'" was considered to be
   a designator even if it wasn't the first in a designator list.
3. In the "identifier ':'" case, it actually builds the designator
   representation.

Don't give a default argument to ASTContext::getFunctionType for the TypeQuals parameter, it causes subtle bugs where TypeQuals, while necessary, are omitted from the call.
-Remove the default argument.
-Update all call sites of ASTContext::getFunctionType.

Add a default constructor to AsmWriterOperand to make VS2008sp1 happy. (AsmWriterOperand is used in a std::pair, and VS need to generate the default constructor of this pair).
