James Y Knight 9de6d7becc Stop increasing alignment of externally-visible globals on ELF
platforms.

With ELF, the alignment of a global variable in a shared library will
get copied into an executables linked against it, if the executable even
accesss the variable. So, it's not possible to implicitly increase
alignment based on access patterns, or you'll break existing binaries.

This happened to affect libc++'s std::cout symbol, for example. See

Chih-Hung Hsieh 578864007b [TLS] New lower emutls pass, fix linkage bugs.
Previous implementation in http://reviews.llvm.org/D10522
created external references to __emutls_v.* variables.
Such references are inaccurate and cannot be handled by
all linkers, e.g. Android dynamic and gold linkers for aarch64.

Now a new LowerEmuTLS pass to go through all global variables,
and add emutls_v.* and emutls_t.* variables.
These __emutls* variables have the same linkage and
visibility as the associated user defined TLS variable.

Also removed old code that dump __emutls* variables in AsmPrinter.cpp,
and updated TLS unit tests.

Todd Fiala 02fe4b9334 change Xcode test run default to ignore xpass on Xunit output
The Green Dragon LLVM builders are starting to parse xunit output
on LLDB Xcode builders.  By default the XML formatter treats
xpass (unexpected successes) as failures.  The new flag added
ensures we simply ignore those for purposes of xUnit output.
LLDB is not currently XPASS clean.

Xinliang David Li a9d784666e [Coverage] introduce class hierarchy (funcRecordReader) to support multiple versions of coverage data
[resubmit after fixing build bot failures: qualify make_unique and eliminate -Wcovered-switch-default warning.
With the planned size reduction change, the coverage format version is expected to be bumped up. This patch adds necessary support such that backward compatibility can be kept with maximal code sharing. Reading different versions of coverage data just requires instantiating the reader according to the version.

No functional change is intended.

Easwaran Raman 183ebbe0ee Display detailed profile summary in llvm-profdata tool.
This adds a detailed profile summary in llvm-profdata. The summary is in the
form of one or more triples of the form (P, N, M) which is interpreted as if
we look at the Top-N counts in the profile, their sum accounts for P percentage
of the sum of all counts in the program and the minimum count in the Top-N is M.

Zachary Turner 19e2ea8fb6 Fix TestProcessLaunch for Python 3.
There were a number of problems preventing this from working:

1. The SWIG typemaps for converting Python lists to and from C++
   arrays were not updated for Python 3.  So they were doing things
   like PyString_Check instead of using the PythonString from
   PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
   So any test that involved launching an inferior with any kind
   of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
   implemented on Windows.  So this was changed to save the
   value of the environment variable in a local variable and
   have the debugger look at the value of the variable.
