Craig Topper f441226085 [TableGen] Remove RecordVal constructor that takes a StringRef and Record::setName(StringRef). Leave just the versions that take an Init.
They weren't used often enough to justify having two different interfaces. Push the responsiblity of creating a StringInit up to the caller.

Craig Topper 2b8419a22d [TableGen] Make Record::getValueAsString and getValueAsListOfStrings return StringRefs instead of std::string
Internally both these methods just return the result of getValue on either a StringInit or a CodeInit object. In both cases this returns a StringRef pointing to a string allocated in the BumpPtrAllocator so its not going anywhere. So we can just pass that StringRef along.

This is a fairly naive patch that targets just the build failures caused by this change. There's additional work that can be done to avoid creating std::string at call sites that still think getValueAsString returns a std::string. I'll try to clean those up in future patches.

Craig Topper 638b1021bf [TableGen] Use StringMap instead of DenseMap<StringRef> to unique CodeInit and StringInit objects. Override the allocator to keep using the BumpPtrAllocator. NFCI
StringMap is better suited to mapping strings than a DenseMap.

Craig Topper a568c72b7d [TableGen] Prevent DagInit from leaking its Args and ArgNames when they exceed the size of the SmallVector.
DagInits are allocated in a BumpPtrAllocator so they are never destructed. This means the destructor for the SmallVector never runs.

To fix this we now allocate the vectors in the BumpPtrAllocator too using TrailingObjects.

Craig Topper b8ff353fc6 [TableGen] Remove all the static vectors named TheActualPool.
These used to hold std::unique_ptrs that managed the allocation for the various *Init object so that they would be deleted on exit. Everything is allocated in a BumpPtrAllocator name so there is no reason for these to still exist.

Matthias Braun 8c209aa877 Cleanup dump() functions.
We had various variants of defining dump() functions in LLVM. Normalize
them (this should just consistently implement the things discussed in
http://lists.llvm.org/pipermail/cfe-dev/2014-January/034323.html

For reference:
- Public headers should just declare the dump() method but not use
  LLVM_DUMP_METHOD or #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
- The definition of a dump method should look like this:
  #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
  LLVM_DUMP_METHOD void MyClass::dump() {
    // print stuff to dbgs()...
  }
  #endif

Matthias Braun 6a441839a6 TableGen: Use more StringInit instead of StringRef
This forces the code to call StringInit::get on the string early and

Benjamin Kramer 46e38f3678 Avoid copies of std::strings and APInt/APFloats where we only read from it
As suggested by clang-tidy's performance-unnecessary-copy-initialization.
This can easily hit lifetime issues, so I audited every change and ran the
tests under asan, which came back clean.

Matt Arsenault a7bc7db53c TableGen: Support folding casts from bits to int
This is to fix an incorrect error when trying to initialize
DwarfNumbers with a !cast<int> of a bits initializer.
getValuesAsListOfInts("DwarfNumbers") would not see an IntInit
and instead the cast, so would give up.

It seems likely that this could be generalized to attempt
the convertInitializerTo for any type. I'm not really sure
why the existing code seems to special case the string cast cases
when convertInitializerTo seems like it should generally handle this
sort of thing.
