f560ffae1f Make isOperationLegal do what its name suggests, and introduce a 
new isOperationLegalOrCustom, which does what isOperationLegal
previously did.

Update a bunch of callers to use isOperationLegalOrCustom
instead of isOperationLegal. In some case it wasn't obvious
which behavior is desired; when in doubt I changed then to
isOperationLegalOrCustom as that preserves their previous
behavior.

This is for the second half of PR3376.

1632782fe9 The memory alignment requirement on some of the mov{h|l}p{d|s} patterns are 16-byte. That is overly strict. These instructions read / write f64 memory locations without alignment requirement.

72bb40229e 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 :)

ce9bc12c6f Add an assertion to the form of SelectionDAG::getConstant that takes

to help catch accidental overflow. Fix a few places that relied on
getConstant implicitly truncating the value.

2d0f1c57c3 APInt's countLeadingOnes() was broken for negative i128 values,
