085bede949 [UBSan] Make stacktrace-matching CHECK-lines in tests Linux-specific.
Darwin doesn't yet allow to print stack trace, as it lacks the slow
unwinder. This is one more attempt to fix vptr.cpp on Mac OS X.

2d2faae647 profile: Use unique directory for tests that write default profile file
Fix a couple of new tests that were reverted because they were causing
intermittent test failures since they were writing the same default
"default.profraw" file. Fixed by creating a unique directory and
running tests in that directory.

Patch by Teresa Johnson. Thanks!

299c21474c [UBSan] Various improvements to vptr.cpp test case
* Remove __ubsan_default_options, so that test would work on Darwin
* Fix unintentional undefined behavior in the code (missing return)
* Build the test with -fno-sanitize-recover to distinguish expected
  failures and expected passes by return code.

d641b53f93 This change is the first of 3 patches to add support for specifying
the profile output from the command line via -fprofile-instr-generate=<path>,
where the specified output path/file will be overridden by the
LLVM_PROFILE_FILE environment variable.

Several changes are made to the runtime to support this:

Add a new interface __llvm_profile_override_default_filename that will
set the profile output filename, but allows LLVM_PROFILE_FILE to override.
This is the interface used by the new option.

Refactor the pid-expansion done for LLVM_PROFILE_FILE into a separate
routine that can be shared by the various filename setting routines
(so that the filename from the option can also use the "%p" syntax).

Move the truncation into setFilename, and only truncate if there is a
new filename specified (to maintain support for appending to the same
profile file in the case of multiple shared objects built with profiling).

Move the handling for a NULL filename passed to __llvm_profile_set_filename and
__llvm_profile_override_default_filename into the new setFilenamePossiblyWithPid
routine. This now correctly resets the output file to default.profraw
instead of NULL.
The handling for a null LLVM_PROFILE_FILE (which should not reset) is done
by caller setFilenameFromEnvironment.

0568283e69 [asan] Print SHADOW_SCALE and SHADOW_GRANULARITY as decimal values.
Summary:
During the review of http://reviews.llvm.org/D9199 where I had originally
changed the debug_mapping.cc test to accept hexadecimal values, we realized
that SHADOW_SCALE and SHADOW_GRANULARITY ought to be printed as decimal values.
This patch makes that change.

This patch also adds a '0x' prefix to the SHADOW_OFFSET to make it clear that
it is hexadecimal while the other two are decimal.

cbdd0dc88a [lsan] Add an interface function for on-demand leak checking.
Summary:
Add an interface function which can be used to periodically trigger
leak detection in a long-running process.

NB: The meaning of the kIgnored tag has been changed to allow easy clean-up
between subsequent leak checks. Previously, this tag was applied to explicitly
ignored (i.e. with __lsan_disable() or __lsan_ignore_object()) chunks *and* any
chunks only reachable from those. With this change, it's only applied to
explicitly ignored chunks.

eb0ebc367e Add COMPILER_RT_ABI attribute to declarations of builtin functions in unittests
Summary:
This makes their local declarations match their definitions for ARM targets,
where they have a different calling convention.

This really only affects functions that use floating point types (since the
runtime functions use soft-float, and some targets may default to hard-float)
but it seemed good to make it uniform and do the int-only ones too.

9316d89d55 [asan] debug_mapping.cc should also pass when the leading digit of SHADOW_SCALE is hexadecimal.
Summary:
Previously the CHECK directive for SHADOW_SCALE only matched decimal digits
causing it to match '7' on x86_64 instead of the whole value.

This fixes a failure on mips-linux-gnu targets where the leading digit is 'a'.

ffa272ebbb [mips] Support building compiler-rt with gcc.
Summary:
This will allow us to enable it on the buildbot (and then enable a
sanitizer buildbot).

The problem is that gcc for Mips does not accept -m32/-m64 like clang does.
We therefore need to use the nearest equivalent -mips32r2/-mips64r2. We must
also specify -mabi=64 in the -mips64r2 case since gcc's default ABI has
traditionally been N32 whereas clang's is N64.
