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.

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.

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.

On ppc64le Fedora 21, getpwnam_r("no-such-user", ...) returns ENOENT

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'.

float-cast-overflow handler doesn't have source location provided by the
compiler, but we still have *some* source location if we have a
symbolizer.

Summary:
ubsan was correctly catching the undefined behaviour but lit's shell was
failing the test anyway because the exit code was non-zero as a result of the
undefined behaviour.
This fixes the test on a mips-linux-gnu target.

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.

As with the other sanitizers, it is desirable to allow ubsan's output to be

After some investigation, it turns out to be due to the regex used for search test_ symbols in lib/dfsan/scripts/check_customer_wrappers.sh:
grep -E "^\\s*test_.*\(\);" ${DFSAN_CUSTOM_TESTS}
This uses \s to search for whitespace at start of line, but support for \s was only introduced in GNU grep v2.5.4-112-gf979ca0, while both FreeBSD and OSX only have grep 2.5.1 (the last version released under GPLv2).
I propose to change \s into [[:space:]], which is the more portable notation.
Test Plan: Run regression tests, and see that they work now. :)
