Summary:
Triple components in `XFAIL` lines are tested against the target triple.
Various tests that are expected to fail on big-endian hosts are marked
as being `XFAIL` for big-endian targets. This patch corrects these tests
by having them test against a new `host-byteorder-big-endian` feature.

Add powerpc- (32-bit) as XFAIL for tests that are documented either in-
line or via commit messages as expected to fail on big-endian systems.
Tests not documented in-line are documented in commit messages as
follows:
r211172 - test/tools/llvm-cov/llvm-cov.test
r247920 - test/Transforms/SampleProfile/gcc-simple.ll

In order for recent gcov versions to read the coverage data, you have
to use UseCfgChecksum=true and FunctionNamesInData=false options for
coverage profiling pass. This is because gcov is expecting the
function section in .gcda to be exactly 3 words in size, containing
ident and two checksums.
While llvm-cov is compatible with UseCfgChecksum=true, it always
expects a function name in .gcda function sections (it's not
compatible with FunctionNamesInData=false). Thus it's currently
impossible to generate one set of coverage files that works with both
gcov and llvm-cov.
This change fixes the reading of coverage information to only read the
function name if it's present.
