a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. 
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

PR6240.

3d33fab7fc Reapply r95393, without the change to CGExpr. I was wrong in assuming that the 
element type always matched the converted LLVM type for ExprType.

363589bded IRgen: Use hasAggregateLLVMType instead of isSingleValueType() for cases that 
need to deal with aggregates specially; this is consistent with the rest of IRgen.

Also, simplify EmitParmDecl and don't worry about using Decl::getNameAsString.

40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

01e620efaa Change the return type of ASTContext::getTypeSizeInChars() from uint64_t to the 
new opaque value type, CharUnits. This will help us avoid accidentally mixing 
quantities that are in bit and character units.

acfe6aa83a Rename getByteSize() and getTypeSizeInBytes() in ASTContext to getCharWidth() 
and getTypeSizeInChars() to reflect their basis in character type units, not
that of a possibly independent architecture-specific byte.
