In -output-dir mode, file reports are placed into a "coverage"
directory. If filenames in the coverage mapping contain "..", they might
escape out of this directory.
Fix the problem by removing ".." from source filenames (expand the path
component).

- Add renderView{Header,Footer}, renderLineSuffix, and hasSubViews to
support creating tables with nested views.
- Move the 'Format' cl::opt to make it easier to extend.
- Just create one function view file, instead of overwriting the same
file for every new function. Add a regression test for this.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.

If a sub-view has already been rendered, it's helpful to re-render the
expansion site before rendering the next expansion view. Make this fact
explicit in the rendering interface, instead of hiding it behind an
awkward Optional<LineRef> parameter.
llvm-svn: 273789
This makes it easier to add renderers for new kinds of output formats.
- Define and document a pure-virtual coverage rendering interface.
- Move the text-based rendering logic into its a new file.
- Re-work the API to better reflect the presentation/formatting split.

A SourceName can be a file or a function. It makes sense to attach this
information to a SourceCoverageView, seeing as views (1) already point
to the text corresponding to the relevant source code and (2) are
already used to render that text along with the SourceNames.
This is a nice cleanup which is independent of the upcoming html patch.
While we're at it, document the fields in SourceCoverageView.
llvm-svn: 273634
Pull LineCoverageInfo out of SourceCoverageView and rename it so that it
doesn't conflict with another class of the same name in
CoverageSummaryInfo.h.
This cuts down on the amount of code we have to move into a `protected`
section of SourceCoverageView for the upcoming html patch. It also makes
the code a bit clearer: having two LineCoverageInfo's is strange.

Transition InstrProf and Coverage over to the stricter Error/Expected
interface.
Changes since the initial commit:
- Fix error message printing in llvm-profdata.
- Check errors in loadTestingFormat() + annotateAllFunctions().
- Defer error handling in InstrProfIterator to InstrProfReader.
- Remove the base ProfError class to work around an MSVC ICE.

Coverage mapping data is organized in a sequence of blocks, each of which is expected
to be aligned by 8 bytes. This feature is used when reading those blocks, see
VersionedCovMapFuncRecordReader::readFunctionRecords(). If a misaligned covearge
mapping data has more than one block, it causes llvm-cov to fail.

Produce the first specific error message for a malformed Mach-O file describing
the problem instead of the generic message for object_error::parse_failed of
"Invalid data was encountered while parsing the file”. Many more good error
messages will follow after this first one.
This is built on Lang Hames’ great work of adding the ’Error' class for
structured error handling and threading Error through MachOObjectFile
construction. And making createMachOObjectFile return Expected<...> .
So to to get the error to the llvm-obdump tool, I changed the stack of
these methods to also return Expected<...> :
object::ObjectFile::createObjectFile()
object::SymbolicFile::createSymbolicFile()
object::createBinary()
Then finally in ParseInputMachO() in MachODump.cpp the error can
be reported and the specific error message can be printed in llvm-objdump
and can be seen in the existing test case for the existing malformed binary
but with the updated error message.
Converting these interfaces to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now use of
errorToErrorCode() and errorOrToExpected() are used where the callers
are yet to be converted.
Also there some were bugs in the existing code that did not deal with the
old ErrorOr<> return values. So now with Expected<> since they must be
checked and the error handled, I added a TODO and a comment:
“// TODO: Actually report errors helpfully” and a call something like
consumeError(ObjOrErr.takeError()) so the buggy code will not crash
since needed to deal with the Error.
Note there is one fix also needed to lld/COFF/InputFiles.cpp that goes along
with this that I will commit right after this. So expect lld not to built
after this commit and before the next one.

Summary:
This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html

The reason we need to search by name rather than by Triple::ArchType
is to handle subarchitecture correclty. There is no different ArchType
for the x86_64h architecture (it identifies itself as x86_64), or for
the various ARM subarches. The only way to get to the subarch slice
in an universal binary is to search by name.
This issue led to hard to debug and transient symbolication failures
in Asan tests (it mostly works, because the files are very similar).
This also affects the Profiling infrastucture as it is the other user
of that API.

In r233132 we started requiring a subcommand in llvm-cov, but this
made `llvm-cov --version` invalid, which is kind of silly. Print
version information in this case, as most people would expect.

If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.
Call sites were found with the ASTMatcher + some semi-automated cleanup.
memberCallExpr(
argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),
hasArgument(0, bindTemporaryExpr(
hasType(recordDecl(hasNonTrivialDestructor())),
has(constructExpr()))),
unless(isInTemplateInstantiation()))

llvm-cov was truncating numbers that were larger than a particular
fixed width, which is as confusing as it is useless. Instead, we use
engineering notation with SI prefix for magnitude.
