This partially reverts r187641 until ld64 adopts a change to link with an
rpath setting.

Linux cannot open directories with open(2), although cygwin and *bsd can.

Motivation: The test, Object/directory.ll, had been failing with --target=cygwin on Linux. XFAIL was improper for host issues.

This will allow for much easier testing when the input files are in a
different folder from the test script.

Added -o option to llvm-cov. If no output file is specified, it defaults
to STDOUT.

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.

  - 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.

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.

This reverts commit r193255 and instead creates an lto_bool_t typedef
that points to bool, _Bool, or unsigned char depending on what is
available.  Only recent versions of MSVC provide a stdbool.h header.

This provides rudimentary testing of the llvm-c api.

The following commands are implemented:

  * --module-dump
    Read bytecode from stdin - print ir

  * --module-list-functions
    Read bytecode from stdin - list summary of functions

  * --module-list-globals
    Read bytecode from stdin - list summary of globals

  * --targets-list
    List available targets

  * --object-list-sections
    Read object file from stdin - list sections

  * --object-list-symbols
    Read object file from stdin - list symbols (like nm)

  * --disassemble
    Read lines of triple, hex ascii machine code from stdin - print disassembly

  * --calc
    Read lines of name, rpn from stdin - print generated module ir

- Replaced tabs with proper padding
- print() takes two arguments, which are the GCNO and GCDA filenames
- Files are listed at the top of output, appended by line 0
- Stripped strings of trailing \0s
- Removed last two lines of whitespace in output

collectLineCounts() should only organize the output data. This is done in
anticipation of subsequent changes which will pass in GCNO and GCDA filenames
into the print function where it is printed similar to the gcov output.

Destroying the codegen also frees the path of the created object. Copy the

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.

We previously failed to check whether the SUCCESS variable was set,
and would thus always exit with a failure if vs2012 didn't exist.
