bc011af4a0 Rewrite the addAttr() method. 
This now uses the AttributeSet object instead of the Attribute /
AttributeWithIndex objects. It's fairly simple now. It goes through all of the
subsets before the one we're modifying, adds them to the new set. It then adds
the modified subset. And then adds the rest of the subsets.

e02fd3448b Revert r173646, "Use proper type for the index." 
Unfortunately, msvc miscompiles it. Investigating.

d8d5c37332 Hide the method that creates an AttributeSet with AttributeWithIndexes. 
This method will go away once AttributeWithIndex goes away. In the meantime,
hide it from general use.

cb286de665 PR14566: Debug Info: Removing top level lexical blocks 
This adds support for LLVM to accept metadata that doesn't include a top level
lexical block in a function. Specifically LLVM couldn't handle this when there
were file changes relating to these blocks. I've updated a few test cases to
ensure other functionality (such as inlining) isn't affected by this change, but
haven't pervasively updated all the test cases.

class. However, that class should be opaque. Allow access through accessor

9e0064d80b Add the IR attribute 'sspstrong'. 
SSPStrong applies a heuristic to insert stack protectors in these situations:

* A Protector is required for functions which contain an array, regardless of
  type or length.

* A Protector is required for functions which contain a structure/union which
  contains an array, regardless of type or length.  Note, there is no limit to
  the depth of nesting.

* A protector is required when the address of a local variable (i.e., stack
  based variable) is exposed. (E.g., such as through a local whose address is
  taken as part of the RHS of an assignment or a local whose address is taken as
  part of a function argument.)

This patch implements the SSPString attribute to be equivalent to
SSPRequired. This will change in a subsequent patch.
