Now -shlib flag can be provided alongside with names of symbols files:

(lldb) target symbols add --shlib stripper-lib.so unstripper-lib.so

This is helpful when default matching mechanisms by name and UUID
can't find a module, and the user needs to explicitly specify
which module the given symbol file belongs to.

Revert "[X86][InlineAsm][Ms Compatibility]Prefer variable name over a register when the two collides"

This reverts r308867 and r308866.

It broke the sanitizer-windows buildbot on C++ code similar to the
following:

  namespace cl { }
  void f() {
    __asm {
      mov al, cl
    }
  }

t.cpp(4,13):  error: unexpected namespace name 'cl': expected expression
    mov al, cl
            ^

In this case, MSVC parses 'cl' as a register, not a namespace.

This reverts commit 15425f2bc6eac6249ee957a2a280511306c07547.

Should work now that atos is a default symbolizer on Darwin.

llvm-svn: 308910

This patch doesn't modifay any non test file.

llvm-svn: 308909

atos is the default symbolizer on Apple's compiler for quite a few years now.
llvm-symbolizer is quite fragile on Darwin: for example, unless a .dSYM
file was explicitly generated symbolication would not work.
It is also very convenient when the behavior of LLVM open source
compiler matches to that of Apple's compiler on Apple's platform.
Furthermore, llvm-symbolizer is not installed on Apple's platform by
default, which leads to strange behavior during debugging: the test
might fail under lit (where it has llvm-symbolizer) but would run
properly when launched on the command line (where it does not, and atos
would be used).

Indeed, there's a downside: atos does not work properly with inlined
functions, hence the test change.
We do not think that this is a major problem, as users would often
compile with -O0 when debugging, and in any case it is preferable to
symbolizer not being able to symbolize.

Under Windows Itanium, we need to export virtual and non-virtual thunks
if the functions being thunked are exported. These thunks would
previously inherit their dllexport attribute from the declaration, but
r298330 changed declarations to not have dllexport attributes. We
therefore need to add the dllexport attribute to the definition
ourselves now. This is consistent with MinGW GCC's behavior.

This redoes r306770 but limits the logic to Itanium. MicrosoftCXXABI's
setThunkLinkage ensures that thunks aren't exported under that ABI, so
I'm handling this in ItaniumCXXABI's setThunkLinkage for symmetry.

We need to export these thunks because they can be referenced outside
the library they're defined in. For example, if a child class without a
key function inherits from a parent class with a key function, the
parent's thunks will only be defined in the library with the key
function, but the construction vtable for the parent in the child might
be emitted outside the library (since the child doesn't have a key
function), and it needs to reference the parent's thunks.

We don't need to mark these thunks as imported since any references to
them will occur in data, so the compiler can't generate the IAT load
sequence anyway. Instead, we rely on the linker generating import thunks
for the thunks.
