Remove trailing whitespace.

llvm-svn: 332220

Summary:
The first foray into merging debug info into the echo tests.

- Add bindings to Module::getModuleFlagsMetadata() in the form of LLVMCopyModuleFlagsMetadata
- Add the opaque type LLVMModuleFlagEntry to represent Module::ModuleFlagEntry
- Add accessors for LLVMModuleFlagEntry's behavior, key, and metadata node.

Noticed by Simon Pilgrim.

This pass is
  a) broken.
  b) r600 specific.

Fixing (a) is a bit more non-trivial, but fixing (b)
is easy. Move this pass to being R600 only for now.

This pass does pass all the unit tests, however clang
no longer generates code that looks like the unit test
input, so fixing the pass requires fixing the tests and
the pass as one, and checking it works with clang still.

comment in the same revision but missed it.

Thanks to Dimitry Andric for catching this!

llvm-svn: 332177

Summary:
As reported in PR37264, in some cases the X86 Domain Reassignment
`runOnMachineFunction()` is called twice.  Because it only deletes the
`.second` members of its `InstrConverterBaseMap`, and does not clean up
the map itself, this can lead to double frees and crashes.

Use `DeleteContainerSeconds()` instead, so the `Converters` map can
safely be reinitialized and its members re-deleted for each X86 Domain
Reassignment pass.

Summary:
InitLLVM already calls llvm_shutdown, but llc registers for shutdown
with llvm_shutdown_obj so it gets called twice. It's not hurting anything, but
it's also not useful, so don't do it.

Stage3/stage4 bootstrap miscompares should be fixed by a non-determinism
fix in IDF (r332167).

This reverts commit r330446.

llvm-svn: 332168

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.
