ba0f991a78 [weak vtables] Place class definitions into anonymous namespaces to prevent weak vtables.
This patch places class definitions in implementation files into anonymous
namespaces to prevent weak vtables. This eliminates the need of providing an
out-of-line definition to pin the vtable explicitly to the file.

354362524a [weak vtables] Remove a bunch of weak vtables
This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file. The memory leaks in this version have been fixed. Thanks
Alexey for pointing them out.

b21ab43cfc Revert r194865 and r194874.
This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
  Base *foo = new Child();
  delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

7e667c56cf Use LTO_SYMBOL_SCOPE_DEFAULT_CAN_BE_HIDDEN instead of the "dso list".
There are two ways one could implement hiding of linkonce_odr symbols in LTO:
* LLVM tells the linker which symbols can be hidden if not used from native
  files.
* The linker tells LLVM which symbols are not used from other object files,
  but will be put in the dso symbol table if present.

GOLD's API is the second option. It was implemented almost 1:1 in llvm by
passing the list down to internalize.

LLVM already had partial support for the first option. It is also very similar
to how ld64 handles hiding these symbols when *not* doing LTO.

This patch then
* removes the APIs for the DSO list.
* marks LTO_SYMBOL_SCOPE_DEFAULT_CAN_BE_HIDDEN all linkonce_odr unnamed_addr
  global values and other linkonce_odr whose address is not used.
* makes the gold plugin responsible for handling the API mismatch.

f61049b2d8 MCJIT-remote: __main should be resolved in child context.
- Mark tests as XFAIL:cygming in test/ExecutionEngine/MCJIT/remote.
    Rather to suppress them, I'd like to leave them running as XFAIL.
  - Revert r193472. RecordMemoryManager no longer resolves __main on cygming.

There are a couple of issues.

  - X86 Codegen emits "call __main" in @main for targeting cygming.
    It is useless in JIT. FYI, tests are passing when emitting __main is disabled.
  - Current remote JIT does not resolve any symbols in child context.

FIXME: __main should be disabled, or remote JIT should resolve __main.

69f4280b54 [bugpoint] Increase the default memory limit for subprocesses to 300MB.
Summary:
Currently shared library builds (BUILD_SHARED_LIBS=ON in cmake) fail three
bugpoint tests (BugPoint/remove_arguments_test.ll,
BugPoint/crash-narrowfunctiontest.ll, and BugPoint/metadata.ll).

If I run the bugpoint commands that llvm-lit runs with without -silence-passes
I see errors such as this:
    opt: error while loading shared libraries: libLLVMSystemZInfo.so: failed to
    map segment from shared object: Cannot allocate memory

It seems that the increased size of the binaries in a shared library build is
causing the subprocess to exceed the 100MB memory limit. This patch therefore
increases the default limit to a level at which these tests pass.

4bad07fbec Fixing problems in lli's RemoteMemoryManager.
This fixes a problem from a previous check-in where a return value was omitted.

Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing.  Those tests attempt to link against an external symbol and remote symbol resolution is not supported.  The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice.  With this check-in remote symbol resolution fails, and so the test (correctly) fails.
