920118470d Add three new option properties. 
Adds new option properties 'multi_val', 'one_or_more' and 'zero_or_one'.

0efa2bd617 Use ZERO_EXTEND instead of ANY_EXTEND when promoting 
shift amounts, to avoid implicitly assuming that
target architectures will ignore the high bits.

7e63f1aae6 Treat [1 x i8] zeroinitializer as a C string, placing such stuff into 
mergeable string section. I don't see any bad impact of such decision
(rather then placing it into mergeable const section, as it was before),
but at least Darwin linker won't complain anymore.

The problem in LLVM is that we don't have special type for string constants
(like gcc does). Even more, we have two separate types: ConstatArray for non-null
strings and ConstantAggregateZero for null stuff.... It's a bit weird :)

0400e83ed8 Add an assertion to the form of SelectionDAG::getConstant that takes 
a uint64_t to verify that the value is in range for the given type,
to help catch accidental overflow. Fix a few places that relied on
getConstant implicitly truncating the value.

47c303034d APInt's countLeadingOnes() was broken for negative i128 values, 
causing assertion failures in getSExtValue().
Fix it by making highWordBits actually contain what its name says,
and add some more unit-tests for APInt.
This fixes PR3419.

4353517ac4 Assorted debug info fixes. 
- DW_AT_bit_size is only suitable for bitfields.
- Encode source location info for derived types.
- Source location and type size info is not useful for subroutine_type (info is included in respective DISubprogram) and array_type.

4ad174b236 Fix the Red Zone calculation for functions with frame pointers. 
Don't use the Red Zone when dynamic stack realignment is needed.
This could be implemented, but most x86-64 ABIs don't require
dynamic stack realignment so it isn't urgent.

276b736496 Fix PR3393, which amounts to a bug in the expensive 
checking logic.  Rather than make the checking more
complicated, I've tweaked some logic to make things
conform to how the checking thought things ought to
be, since this results in a simpler "mental model".

834f011a63 Fix an issue where LiveIntervals was trying to be smart about removing kill 
markers, and ended up foiling the interval reconstruction.

This allows us to turn on reconstruction in the pre alloc splitter, which
fixes a number of miscompilations.

ec03e0cd3b Enhance logic in X86DAGToDAGISel::PreprocessForRMW which move load inside callseq_start to allow it to be folded into a call. It was not considering the cases where a token factor is between the load and the callseq_start.
