13ba2dab63 Use an IndexedMap instead of a DenseMap for the live-out cache. 
This speeds up updateSSA() so it only accounts for 5% of the live range
splitting time.

e7147dba73 There are times when the landing pad won't have a call to 'eh.selector' in 
it. It's been assumed up til now that it would be in its immediate
successor. However, this isn't necessarily the case. It could be in one of its
successor's successors.

Modify the code to more thoroughly check for an 'eh.selector' call in
successors. It only looks at a successor if we get there as a result of an
unconditional branch.

Testcase ObjC/exceptions-4.m in r126968.

f37712f486 Represent sentinel slot indexes with a null pointer. 
This is much faster than using a pointer to a ManagedStatic object accessed with
a function call. The greedy register allocator is 5% faster overall just from
the SlotIndex default constructor savings.

a97ff8a027 Avoid comparing invalid slot indexes, and assert that it doesn't happen. 
The SlotIndex created by the default construction does not represent a position
in the function, and it doesn't make sense to compare it to other indexes.

38c4e53549 Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

9763e2bf39 Move LiveIntervalMap::extendTo into LiveInterval itself. 
This method could probably be used by LiveIntervalAnalysis::shrinkToUses, and
now it can use extendIntervalEndTo() which coalesces ranges.

e9e16c5f52 Today, the language front ends produces llvm.dbg.* intrinsics, used to encode arguments' debug info, in order any way, most of the times. However, if a front end mix-n-matches llvm.dbg.declare and llvm.dbg.value intrinsics to encode debug info for arguments then code generator needs a way to find argument order. 
Use 8 bits from line number field to keep track of argument ordering while encoding debug info for an argument. That leaves 24 bit for line no, DebugLoc also allocates 24 bit for line numbers. If a function has more than 255 arguments then rest of the arguments will be ordered by llvm.dbg.* intrinsics' ordering in IR.

9f0512d85f Change directory_entry::path() to return a const std::string & instead of 
a StringRef, for the benefit of clients that want the result as a

the implicit conversion.
