22af148912 Revert "[ExecutionEngine] Use std::function rather than a function pointer for the LazyFunctionCreator."
This reverts commit r241962, as it was breaking all ARM buildbots.

It also reverts the two subsequent related commits:

r241974: "[ExecutionEngine] Add a static cast to the unittest for r241962 to suppress a warning."

r241973: "[ExecutionEngine] Remove cruft and fix a couple of warnings in the test case for r241962."

ee0d992b07 Add support for fast-math flags to the FCmp instruction.
FCmp behaves a lot like a floating-point binary operator in many ways,
and can benefit from fast-math information. Flags such as nsz and nnan
can affect if this fcmp (in combination with a select) can be treated
as a fminnum/fmaxnum operation.

This adds backwards-compatible bitcode support, IR parsing and writing,
LangRef changes and IRBuilder changes. I'll need to audit InstSimplify
and InstCombine in a followup to find places where flags should be
copied.

c098b6e6e2 Change APInt comparison with uint64_t.
Summary:
This patch changes the way APInt is compared with a value of type uint64_t.
Before the uint64_t value was truncated to the size of APInt before comparison.
Now the comparison takes into account full 64-bit precision.

Test Plan: Unit tests added. No regressions. Self-hosted check-all done as well.

528f9649c8 [DebugInfo] Let IRBuilder::SetInsertPoint(BB::iterator) update current debug location.
IRBuilder::SetInsertPoint(BB, BB::iterator) is an older version of
IRBuilder::SetInsertPoint(Instruction). However, the latter updates
the current debug location of emitted instruction, while the former
doesn't, which is confusing.

Unify the behavior of these methods: now they both set current debug
location to the debug location of instruction at insertion point.

The callers of IRBuilder::SetInsertPoint(BB, BB::iterator) doesn't
seem to depend on the old behavior (keeping the original debug info
location). On the contrary, sometimes they (e.g. SCEV) *should* be
updating debug info location, but don't. I'll look at gdb bots after
the commit to check that we don't regress on debug info somewhere.

This change may make line table more fine-grained, thus increasing
debug info size. I haven't observed significant increase, though:
it varies from negligible to 0.3% on several binaries and self-hosted
Clang.

This is yet another change targeted at resolving PR23837.

717764717b Add a DIModule metadata node to the IR.
It is meant to be used to record modules @imported by the current
compile unit, so a debugger an import the same modules to replicate this
environment before dropping into the expression evaluator.

DIModule is a sibling to DINamespace and behaves quite similarly.
In addition to the name of the module it also records the module
configuration details that are necessary to uniquely identify the module.
This includes the configuration macros (e.g., -DNDEBUG), the include path
where the module.map file is to be found, and the isysroot.

The idea is that the backend will turn this into a DW_TAG_module.

2a5fda92b4 IR: Expose ModuleSlotTracker in Value::print()
Allow callers of `Value::print()` and `Metadata::print()` to pass in a
`ModuleSlotTracker`.  This allows them to pay only once for calculating
module-level slots (such as Metadata).

This is related to PR23865, where there was a huge cost for
`MachineFunction::print()`.  Although I don't have a *particular* user
in mind for this new code, I have hit big slowdowns before when running
`opt -debug`, and I think this will be useful.  Going forward, if
someone hits a big slowdown with `print()` statements, they can create a
`ModuleSlotTracker` and send it through.  Similarly, adding support to
`Value::dump()` and `Metadata::dump()` should be trivial.

I added unit tests to be sure the `print()` functions actually behave
the same way with and without the slot tracker.

2da1484e97 AsmPrinter: Use an intrusively linked list for DIE::Children
Replace the `std::vector<>` for `DIE::Children` with an intrusively
linked list.  This is a strict memory improvement: it requires no
auxiliary storage, and reduces `sizeof(DIE)` by one pointer.  It also
factors out the DIE-related malloc traffic.

This drops llc memory usage from 735 MB down to 718 MB, or ~2.3%.

(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;
see r236629 for details.)

73e3fb6ba8 AsmPrinter: Convert DIE::Values to a linked list
Change `DIE::Values` to a singly linked list, where each node is
allocated on a `BumpPtrAllocator`.  In order to support `push_back()`,
the list is circular, and points at the tail element instead of the
head.  I abstracted the core list logic out to `IntrusiveBackList` so
that it can be reused for `DIE::Children`, which also cares about
`push_back()`.

This drops llc memory usage from 799 MB down to 735 MB, about 8%.

While often you want to use something specialized like StringMap, when

from the hashing code to the endian detection code to CPU feature
detection code to StringMap.

d31dc69aa1 AsmParser: Extend the API to make the global value and metadata node slot mappings publicly accessible.
This commit creates a new structure called 'SlotMapping' in the AsmParser library.
This structure can be passed into the public parsing APIs from the AsmParser library
in order to extract the data structures that map from slot numbers to unnamed global
values and metadata nodes.

This change is useful for MIR Serialization, as the MIR Parser has to lookup the
unnamed global values and metadata nodes by their slot numbers.

0c17f95006 Modify ParseArgs to return the InputArgList by value - there's no need for dynamic allocation/ownership here
The one caller that does anything other than keep this variable on the
stack is the single use of DerivedArgList in Clang, which is a bit more
interesting but can probably be cleaned up/simplified a bit further
(have DerivedArgList take ownership of the InputArgList rather than
needing to reference its Args indirectly) which I'll try to after this.

cc714e2142 Move the personality function from LandingPadInst to Function
The personality routine currently lives in the LandingPadInst.

This isn't desirable because:
- All LandingPadInsts in the same function must have the same
  personality routine.  This means that each LandingPadInst beyond the
  first has an operand which produces no additional information.

- There is ongoing work to introduce EH IR constructs other than
  LandingPadInst.  Moving the personality routine off of any one
  particular Instruction and onto the parent function seems a lot better
  than have N different places a personality function can sneak onto an
  exceptional function.

8e2ed1643a Bring in a BumpPtrStringSaver from lld and simplify the interface.
StringSaver now always saves to a BumpPtrAllocator.

The only reason for having the virtual saveImpl is so lld can have a
thread safe version.

The reason for the distinct BumpPtrStringSaver class is to avoid the
virtual destructor.

21a987d1ac Fix returning error message in LLVMLinkModules
On error, the temporary output stream wouldn't be flushed and therefore the
caller would see an empty error message.
