FileCheck: Add CHECK-SAME
Add `CHECK-SAME`, which requires that the pattern matches on the *same*
line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline
is allowed in the skipped region. This is similar to `CHECK-NEXT`,
which requires exactly 1 newline in the skipped region.
My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy. This allows CHECK sequences like the
following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-SAME: otherField: 93{{[,)]}}
which is equivalent to:
CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}
While this example just has two fields, many nodes in debug info have
more than that. `CHECK-SAME` will keep the logic easy to follow.
Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-NOT: unexpectedField:
CHECK-SAME: otherField: 93{{[,)]}}
CHECK-NOT: otherUnexpectedField:
CHECK-SAME: )
which doesn't seem to have an equivalent `CHECK` line.

Optimize finding the Complete Definition of an ObjC class for debug with .o files with lots of .o files.
When we have a debug map we have an executable with a bunch of STAB symbols and each source file has a N_SO symbol which scopes a bunch of symbols inside of it. We can use this to our advantage here when looking for the complete definition of an objective C class by looking for a symbol whose name matches the class name and whose type is eSymbolTypeObjCClass. If we find one, that symbol will be contained within a N_SO symbol. This symbol gets turned into a symbol whose type is eSymbolTypeSourceFile and that symbol will contain the eSymbolTypeObjCClass which helps us to locate the correct .o file and allows us to only look in that file.
To further accelerate things, if we are looking for the implementation, we can avoid looking at all .o files if we don't find a matching symbol because we have a debug map, which means the objective C symbol for the class can't have been stripped, so we can safely not search all remaining .o files. This will save us lots of time when trying to look for "NSObject" and any other AppKit and Foundation classes that we never have implementation definitions for.

X86, Win64: Allow 'mov' to restore the stack pointer if we have a FP
The Win64 epilogue structure is very restrictive, it permits a very
small number of opcodes and none of them are 'mov'.
This means that given:
mov %rbp, %rsp
pop %rbp
The mov isn't the epilogue, only the pop is. This is problematic unless
a frame pointer is present in which case we are free to do whatever we'd
like in the "body" of the function. If a frame pointer is present,
unwinding will undo the prologue operations in reverse order regardless
of the fact that we are at an instruction which is reseting the stack
pointer.

LowerBitSets: Align referenced globals.
This change aligns globals to the next highest power of 2 bytes, up to a
maximum of 128. This makes it more likely that we will be able to compress
bit sets with a greater alignment. In many more cases, we can now take
advantage of a new optimization also introduced in this patch that removes
bit set checks if the bit set is all ones.
The 128 byte maximum was found to provide the best tradeoff between instruction
overhead and data overhead in a recent build of Chromium. It allows us to
remove ~2.4MB of instructions at the cost of ~250KB of data.

Allow (Object *)kMyGlobalCFObj casts without bridging
Previously we allowed these casts only for constants declared in system
headers, which we assume are retain/release-neutral. Now also allow them
for constants in user headers, treating them as +0. Practically, this
means that we will now allow:
id x = (id)kMyGlobalConst;
But unlike with system headers we cannot mix them with +1 values:
id y = (id)(b ? kMyGlobalConst : [Obj newValAtPlusOne]); // error
id z = (id)(b ? kSystemGlobalConst: [Obj newValAtPlusOne]); // OK

Bugfix: SCEVExpander incorrectly marks increment operations as no-wrap
(The change was landed in r230280 and caused the regression PR22674.
This version contains a fix and a test-case for PR22674).
When emitting the increment operation, SCEVExpander marks the
operation as nuw or nsw based on the flags on the preincrement SCEV.
This is incorrect because, for instance, it is possible that {-6,+,1}
is <nuw> while {-6,+,1}+1 = {-5,+,1} is not.
This change teaches SCEV to mark the increment as nuw/nsw only if it
can explicitly prove that the increment operation won't overflow.
Apart from the attached test case, another (more realistic)
manifestation of the bug can be seen in
Transforms/IndVarSimplify/pr20680.ll.
