Daniel Sanders 93c0f382b4 [mips][msan] Fix all the XPASSes following r278793 and r278795 
All msan tests are now passing for mipsel and mips64el except for
allocator_mapping.cc which is marked unsupported.

Daniel Sanders edfed3deeb [msan] Correct @LINE expression in obstack.cc 
Summary:

[[@LINE-30]] only worked because the resulting 3 matches the first character of
30. With the additional blank lines the resulting 5 no longer matches 30.

Daniel Sanders 67f22ee24a [mips] XFAIL mips64el tests that fail on clang-cmake-mipsel 
These tests were recently enabled and have never worked on this builder.

Three tests were sensitive to line number changes:
  test/msan/Linux/obstack.cc
  test/msan/chained_origin.cc
  test/msan/chained_origin_memcpy.cc
and this sensitivity will be addressed in a follow-up patch. Of these,
obstack.cc's sensitivity to line numbers is unexplained since it already uses
[[@LINE]].

Daniel Sanders 875671185e [mips] Remove obstack.cc XFAIL added in r278504 since it broke X86 and PPC somehow. 
Adding the XFAIL has caused msan to report a different line number in the call
stack (@LINE-3 rather than @LINE-30). The new line number looks more correct
at first glance since it's the line that uses uninitialized memory rather than
the first non-whitespace line of the file but this needs investigating.

Daniel Sanders 6a540c1f38 [mips] XFAIL the new mips64el compiler-rt tests that fail on clang-cmake-mipsel. 
The mips64el compiler-rt build has recently been enabled. XFAIL the failing
tests to make the buildbot green again.

The two asan tests require the integrated assembler. This will be fixed soon
for Debian mips64el but not for any other mips64el targets since doing so
requires triple-related issues to be fixed..
The msan tests are largely failing because caused by a kernel update (a patch
has already been posted for this).
I'm not sure why the dfsan test fails yet.

Evgeniy Stepanov ecfcc07a48 [msan] Don't check dstaddr in sendto() interceptor. 
Dstaddr may contain uninitialized padding at the end (common
implementations accept larger addrlen and ignore the extra bytes).
Also, depending on the socket state, dstaddr argument may be ignored.
