2ef97554d8 ARM: fix folding of stack-adjustment (yet again).
When trying to eliminate an "sub sp, sp, #N" instruction by folding
it into an existing push/pop using dummy registers, we need to account
for the fact that this might affect precisely how "fp" gets set in the
prologue.

We were attempting this, but assuming that *whenever* we performed a
fold it would make a difference. This is false, for example, in:
    push {r4, r7, lr}
    add fp, sp, #4
    vpush {d8}
    sub sp, sp, #8

we can fold the "sub" into the "vpush", forming "vpush {d7, d8}".
However, in that case the "add fp" instruction mustn't change, which
we were getting wrong before.

Should fix PR18160.

72517bc221 Fix inlining to not lose the "cleanup" clause from landingpads

2d856cb007 Fix inlining to not produce duplicate landingpad clauses
Before this change, inlining one "invoke" into an outer "invoke" call
site can lead to the outer landingpad's catch/filter clauses being
copied multiple times into the resulting landingpad.  This happens:

 * when the inlined function contains multiple "resume" instructions,
   because forwardResume() copies the clauses but is called multiple
   times;

 * when the inlined function contains a "resume" and a "call", because
   HandleCallsInBlockInlinedThroughInvoke() copies the clauses but is
   redundant with forwardResume().

Fix this by deduplicating the code.

This problem doesn't lead to any incorrect execution; it's only
untidy.

This change will make fixing PR17872 a little easier.

types.

This also synchronizes the documentation to Types.h, so it refers to first class

2ac3f8f326 Factor out the SchedRemainder/SchedBoundary from GenericScheduler strategy.
These helper classes take care of the book-keeping the drives the
GenericScheduler heuristics. It is likely that developers writing
target-specific schedulers that work similarly to GenericScheduler
will want to use these helpers too. The immediate goal is to develop a
GenericPostScheduler that can run in place of the old PostRAScheduler,
but will use the new machine model.

No functionality change intended.

25f8267b84 Support: Fix handling of args that begin with @ but aren't files
Command line arguments that begin with @ but aren't a path to an
existing file currently cause later @file arguments to be ignored.

Correctly skip over these arguments instead of trying to read a
non-existent file 20 times and giving up.

Since the problem manifests in the clang driver, the test is in that
repository.

ff3935d81d Integrated assembler incorrectly lexes ARM-style comments
The integrated assembler fails to properly lex arm comments when
they are adjacent to an identifier in the input stream. The reason
is that the arm comment symbol '@' is also used as symbol variant in
other assembly languages so when lexing an identifier it allows the
'@' symbol as part of the identifier.

Example:
  $ cat comment.s
  foo:
    add r0, r0@got to parse this as a comment

  $ llvm-mc -triple armv7 comment.s
  comment.s:4:18: error: unexpected token in argument list
    add r0, r0@got to parse this as a comment
                   ^
This should be parsed as correctly as `add r0, r0`.

This commit modifes the assembly lexer to not include the '@' symbol
in identifiers when lexing for targets that use '@' for comments.

c7180b55dc DwarfDebug: Walk skeletons during fission pubtypes/pubnames emission
This more accurately represents the actual walk - pubnames/pubtypes are
emitted into the .o, not the .dwo, and reference the skeletons not the
full units.

Use the newly established ID->index invariant to lookup the underlying
full unit to retrieve its public names and types.

24e2ea8a35 DebugInfo: Ensure unit IDs (for non-skeletal units) match thein index in the list
This simplifies reasoning about the code and enables simple navigation
from a skeleton to its full unit. (currently there are no type unit
skeletons, so the skeleton list doesn't have the same ID == index
property)

Eventually we should get rid of this ID and just store the labels we
need as the IDs are allowing this code to create difficult to
manage/understand associations (loops over non-skeletal units are
implicitly referencing their skeletal units during pub* emission, for
example). It may be necessary to have some kind of skeleton->full unit
association and a more direct pointer or similar device would be
preferable than an index.

f90fe366af Bug 18149: [AArch32] VSel instructions has no ARMCC field
The current peephole optimizing for compare inst assumes an instr that

(vseqeq, vselgt, vselgt, vselvs), there is no such operand nor do
they support the modification of Cond Code.

9be3fcae69 [SystemZ] Optimize selects between 0 and -1
Since z has no setcc instruction as such, the choice of setBooleanContents
is a bit arbitrary.  Currently it's set to ZeroOrOneBooleanContent,
so we produced a branch-free form when selecting between 0 and 1,
but not when selecting between 0 and -1.  This patch handles the latter
case too.

At some point I'd like to measure whether it's better to use conditional
moves for constant selects on z196, but that's future work.

fc32a3e5d2 [asan] rewrite asan's stack frame layout
Summary:
Rewrite asan's stack frame layout.
First, most of the stack layout logic is moved into a separte file
to make it more testable and (potentially) useful for other projects.
Second, make the frames more compact by using adaptive redzones
(smaller for small objects, larger for large objects).
Third, try to minimized gaps due to large alignments (this is hypothetical since
today we don't see many stack vars aligned by more than 32).

The frames indeed become more compact, but I'll still need to run more benchmarks
before committing, but I am sking for review now to get early feedback.

This change will be accompanied by a trivial change in compiler-rt tests
to match the new frame sizes.
