Alexey Samsonov 1eaae4c3b1 [Symbolize] Improve the ownership of parsed objects.
This code changes the way Symbolize handles parsed binaries: now
parsed OwningBinary<Binary> is not broken into (binary, memory buffer)
pair, and is just stored as-is in a cache. ObjectFile components
of Mach-O universal binaries are also stored explicitly in a
separate cache.

Additionally, this change:
* simplifies the code that parses/caches binaries: it's now done
  in a single place, not three different functions.
* makes flush() method behave as expected, and actually clear
  the cached parsed binaries and objects.
* fixes a dangling pointer issue described in

Cong Hou fd0d62b87e Use getEdgeProbability() instead of getEdgeWeight() in BFI and remove getEdgeWeight() interfaces from MBPI.
This patch removes all getEdgeWeight() interfaces from CodeGen directory. As
getEdgeProbability() is a little more expensive than getEdgeWeight(), I will
compose a patch soon in which BPI only stores probabilities instead of edge
weights so that getEdgeProbability() will have O(1) time.

Richard Smith 0f59cb38e7 Wire a SourceLocation into IsDerivedFrom and move the RequireCompleteType call
for the derived class into it. This is mostly just a cleanup, but could in
principle be a bugfix if there is some codepath that reaches here and didn't
previously require a complete type (I couldn't find any such codepath, though).

Bob Wilson 2b2a0ae76d PIC should not be enabled by default on Darwin with -static.
r245667 changed -static so that it doesn't override an explicit -fPIC
option, but -static should still change the default for Darwin for -fno-PIC.
This matches longstanding GCC and Clang behavior on Darwin and changing it
would be disruptive, with no significant benefit.

Alexey Samsonov 081a24e3a7 [UBSan] Implement runtime suppressions (PR25066).
Summary:
Add the ability to suppress UBSan reports for files/functions/modules
at runtime. The user can now pass UBSAN_OPTIONS=suppressions=supp.txt
with the contents of the form:

signed-integer-overflow:file-with-known-overflow.cpp
alignment:function_doing_unaligned_access
vptr:shared_object_with_vptr_failures.so

Suppression categories match the arguments passed to -fsanitize=
flag (although, see below). There is no overhead if suppressions are
not provided. Otherwise there is extra overhead for symbolization.

Limitations:
1) sometimes suppressions need debug info / symbol table to function
   properly (although sometimes frontend generates enough info to
   do the match).
2) it's only possible to suppress recoverable UB kinds - if you've
   built the code with -fno-sanitize-recover=undefined, suppressions
   will not work.
3) categories are fine-grained check kinds, not groups like "undefined"
   or "integer", so you can't write "undefined:file_with_ub.cc".

Pete Cooper 6c97f4c7d7 Improve DWARFDebugFrame::parse to also handle __eh_frame.
LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's.

This code improves DWARFDebugFrame::parse to do the same for parsing.

This also allows llvm-objdump to support the --dwarf=frames option which objdump supports.  This
option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse.

This change promotes load instructions which directly read from stores by
replacing them with mov instructions. If the store is wider than the load,
the load will be replaced with a bitfield extract.
For example :
  STRWui %W1, %X0, 1
  %W0 = LDRHHui %X0, 3

  STRWui %W1, %X0, 1

Rafael Espindola 7a36355b21 Handle archives with paths in the names.
We always create archives with just he filename as the member name, but
other archives can put a more complicated path in there.

This patches handles it by computing just the filename as we do when
adding a new member.

If storing the path is important for some reason, we should probably
have an orthogonal option for doing that and do it for both old and new
members.

Fixes pr25877.

Kuba Brecka f9cc9d7392 [tsan] Fix scoping of ScopedInteceptor in libdispatch support
Some interceptors in tsan_libdispatch_mac.cc currently wrongly use TSAN_SCOPED_INTERCEPTOR/ScopedInterceptor. Its constructor can start ignoring memory accesses, and the destructor the stops this -- however, e.g. dispatch_sync can call user's code, so the ignoring will extend to user's code as well. This is not expected and we should only limit the scope of ScopedInterceptor to TSan code.  This patch introduces annotations that mark the beginning and ending of a callback into user's code.
