calls that don't take a Function argument from Mips. Notable
exceptions: the AsmPrinter and MipsTargetObjectFile. The
latter needs to be fixed, and the former will be fixed when the
general AsmPrinter changes happen.

between the linker's TLS optimizations and Clang's TLS code generation.
For now, Clang has been changed to disable linker TLS optimizations
until it (and LLVM more generally) are emitting TLS code sequences
compatible with the old bugs found in the linkers. That's a better fix
to handle bootstrapping on that platform.

This is just an alias for CALL64pcrel32, and we can just use that opcode
with explicit defs in the MI.
No functionality change.

win64: Call __chkstk through a register with the large code model
Fixes half of PR18582. True dynamic allocas will still have a
CALL64pcrel32 which will fail.

The validation algorithm used an incremental approach, building each
iteration's data structures temporarily, validating them, then
adding them to a global set.
This does not scale well to having multiple sets of Root nodes, as the
set of instructions used in each iteration is the union over all
the root nodes. Therefore, refactor the logic to create a single, simple
container to which later logic then refers. This makes it simpler
control-flow wise to make the creation of the container more complex with
the addition of multiple root sets.

Add tests for the various combines. This should
always be at least cycle neutral on all subtargets for f64,
and faster on some. For f32 we should prefer selecting
v_mad_f32 over v_fma_f32.

The use of the DbgLoc in FastISel is probably something we should fix.
It's prone to leaking the wrong location into instructions - we should
have a clear chain of custody from the debug location of an IR
Instruction to that of a MachineInstr to avoid such leakage.

Certain aspects of llvm-pdbdump require language support only present in
MSVC 2013 and higher. Since this is strictly a utility, and since we hope
to drop support for MSVC 2012 soon, don't build this unless MSVC 2013 or
higher.

Any code creating an MCSectionELF knows ELF and already provides the flags.
SectionKind is an abstraction used by common code that uses a plain
MCSection.
Use the flags to compute the SectionKind. This removes a lot of
guessing and boilerplate from the MCSectionELF construction.

For large stack offsets the compiler generates multiple immediate mode
sub/add instructions in the prologue/epilogue. This patch makes the
compiler place the final amount to be added/subtracted into a register,
which is then added/substracted with a single operation.

Patch by Nemanja Ivanovic.
As was uncovered by the failing test case (when run on non-PPC
platforms), the feature set when compiling with -march=ppc64le was not
being picked up. This change ensures that if the -mcpu option is not
specified, the correct feature set is picked up regardless of whether
we are on PPC or not.

reroll() was slightly monolithic and a pain to modify. Refactor
a bunch of its state from local variables to member variables
of a helper class, and do some trivial simplification while we're
there.
