9550ad611d [CodeView] Add prefix to CodeView registers.
Adds CVReg to CodeView register names to prevent a duplicate symbol with
CR3 defined in termios.h, as suggested by Zachary on the mailing list.

5a4700cb8f [ORC] Add findSymbolIn() wrapper to C bindings, take #2.
Re-appply r333147, reverted in r333152 due to a pre-existing bug. As
D47308 has been merged in r333206, the OSX issue should now be
resolved.

In many cases JIT users will know in which module a symbol
resides. Avoiding to search other modules can be more efficient. It
also allows to handle duplicate symbol names between modules.

This reverts r333147 until https://reviews.llvm.org/D47308 is ready to
be reviewed. r333147 exposed a behavioural difference between
OrcCBindingsStack::findSymbolIn() and OrcCBindingsStack::findSymbol(),
where only the latter does name mangling. After r333147 that causes a
test failure on OSX, because the new test looks for main using
findSymbolIn() but the mangled name is _main.

59d8d97866 Fix build warning compiling TestPlugin on Windows and disable Passes plugin stuff on Windows since it fundamentally can't work
Aaron Ballman reported that TestPlugin warned about it using exception handling
without /EHsc flag, and that llvmGetPassInfo() had conflicting export
attributes (dllimport in the header, dllexport in the source file).

/EHsc is because TestPlugin didn't use the llvm_ cmake functions, so
llvm_update_compile_flags didn't get called for the target
(llvm_update_compile_flags explicitly passes /Ehs-c-, which fixes the warning).
Use add_llvm_loadable_module instead of add_library(... MODULE) to fix this.
This also has the side effect of not building the plugin on Windows. That's not
a big problem, since before the plugin was built on Windows, but the test
didn't attempt to load it, due to -DLLVM_ENABLE_PLUGIN not being passed to
PluginsTests.cpp during compilation on Windows. This makes the plugin behavior
consistent with e.g. lib/Transforms/Hello/CMakeLists.txt. (This also
automatically sets LTDL_SHLIB_EXT correctly.)

The dllimport/dllexport warning is more serious: Since LLVM doesn't generally
use export annotations for its code, the only way the plugin could link was by
linking in some LLVM libraries both into the test and the dll, so the plugin
would call the llvm code in the dll instead of the copy in the main executable.
This means globals weren't shared, and things generally can't work. (I think
there's a build config where you can build a LLVM.dll which might work, but
that wasn't how the test was configured. If that config is used, the dll should
still be built, but I haven't checked).

Now that add_llvm_loadable_module is used, LLVM_LINK_COMPONENTS got linked into
both executable and plugin on posix too, so unset it after the executable so
that the plugin doesn't end up with a 2nd copy of things on posix.

ddc80b6937 [ORC] Consolidate materialization errors, and generate them in VSO's

VSO::notifyFailed is responsible for notifying queries that they will not

cbf403bc80 [ORC] Rewrite the VSO symbol table yet again. Update related utilities.
VSOs now track dependencies for materializing symbols. Each symbol must have its
dependencies registered with the VSO prior to finalization. Usually this will
involve registering the dependencies returned in
AsynchronousSymbolQuery::ResolutionResults for queries made while linking the
symbols being materialized.

Queries against symbols are notified that a symbol is ready once it and all of
its transitive dependencies are finalized, allowing compilation work to be
broken up and moved between threads without queries returning until their
symbols fully safe to access / execute.

Related utilities (VSO, MaterializationUnit, MaterializationResponsibility) are
updated to support dependence tracking and more explicitly track responsibility
for symbols from the point of definition until they are finalized.

a5ef8dbacb Give shared modules in unittests the platform-native extension, make PipSqueak a MODULE
As far as I can tell from revision history, there's no good reason to call
these files .so instead of .dll in Windows, so use the normal extension.

Also change PipSquak from SHARED to MODULE -- it's never passed to
target_link_libraries() and only loaded via dlopen(), so MODULE is more
appropriate. This makes it possible to delete a workaround for SHARED ldflags
being not quite right as well.

49d76cdb55 [CommandLine] Error message for incorrect PositionalEatArgs usage
Summary:
bugpoint has several options specified as `PositionalEatArgs` to pass
options through to the underlying tool, e.g. `-tool-args`. The `-help`
message suggests the usage is: `-tool-args=<string>`. However, this is
misleading, because that's not how these arguments work. Rather than taking
a value, the option consumes all positional arguments until the next
recognized option (or all arguments if `--` is specified at some point).
To make this slightly clearer, instead print the help as:
```
  -tool-args <string>...                            - <tool arguments>...
```
Additionally, add an error if the user attempts to use a `PositionalEatArgs`
argument with a value, instead of silently ignoring it. Example:
```
./bin/bugpoint -tool-args=-mpcu=skylake-avx512
bugpoint: for the -tool-args option: This argument does not take a value.
    Instead, it consumes any positional arguments until the next recognized option.
```

Summary:
Currently the order of blocks returned by `IDF::calculate` can be
non-deterministic. This was discovered in several attempts to enable
SSAUpdaterBulk for JumpThreading (which led to miscompare in bootstrap between
stage 3 and stage4). Originally, the blocks were put into a priority queue with
a depth level as their key, and this patch adds a DFSIn number as a second key
to specify a deterministic order across blocks from one level.

The solution was suggested by Daniel Berlin.
