8f32e5f0d6 Rename llvm.frameescape and llvm.framerecover to localescape and localrecover
Summary:
Initially, these intrinsics seemed like part of a family of "frame"
related intrinsics, but now I think that's more confusing than helpful.
Initially, the LangRef specified that this would create a new kind of
allocation that would be allocated at a fixed offset from the frame
pointer (EBP/RBP). We ended up dropping that design, and leaving the
stack frame layout alone.

These intrinsics are really about sharing local stack allocations, not
frame pointers. I intend to go further and add an `llvm.localaddress()`
intrinsic that returns whatever register (EBP, ESI, ESP, RBX) is being
used to address locals, which should not be confused with the frame
pointer.

Naming suggestions at this point are welcome, I'm happy to re-run sed.

a5106ca54d There are a few places where subtarget features are still
represented by uint64_t, this patch replaces these
usages with the FeatureBitset (std::bitset) type.

1a4def3d97 MIR Serialization: Serialize the register mask machine operands.
This commit implements serialization of the register mask machine
operands. This commit serializes only the call preserved register
masks that are defined by a target, it doesn't serialize arbitrary
register masks.

This commit also extends the TargetRegisterInfo class and TableGen so that
the users of TRI can get the list of all the call preserved register masks and
their names.

09bbd16112 Avoid a Symbol -> Name -> Symbol conversion.
Before this we were producing a TargetExternalSymbol from a MCSymbol.
That meant extracting the symbol name and fetching the symbol again
down the pipeline.

This patch adds a DAG.getMCSymbol that lets the MCSymbol pass unchanged on the
DAG.

Doing so removes the need for MO_NOPREFIX and fixes the root cause of pr23900,
allowing r240130 to be committed again.

1991e2a4df [CodeGen] Introduce a FAULTING_LOAD_OP pseudo-op.
Summary:
This instruction encodes a loading operation that may fault, and a label
to branch to if the load page-faults.  The locations of potentially
faulting loads and their "handler" destinations are recorded in a
FaultMap section, meant to be consumed by LLVM's clients.

Nothing generates FAULTING_LOAD_OP instructions yet, but they will be
used in a future change.

The documentation (FaultMaps.rst) needs improvement and I will update
this diff with a more expanded version shortly.

Depends on D10196

d4b59dcdba [TableGen][AsmMatcherEmitter] Only parse isolated tokens as registers.
Fixes PR23455, where, when TableGen generates the matcher from the
AsmString, it splits "cmp${cc}ss" into tokens, and the "ss" suffix
is recognized as the SS register.

I can't think of a situation where that's a feature, not a bug, hence:
when a token is "isolated", i.e., it is followed and preceded by
separators, it shouldn't be parsed as a register.

ca67e337bf Expand the Flags field of MCInstrDesc to 64 bits, while simultaneously
shrinking the Size and NumDefs fields to offset the size growth, and
reordering the fields to preserve a good packing.

This is necessary in the short term for adding a convergent flag, and
simultaneously future-proofs us against more flags being added in the
future.

75775939fa AsmMatcherEmitter: Add an option to override custom converters for InstAlias
If there is an InstAlias defined for an instruction that had a custom
converter (AsmMatchConverter), then when the alias is matched,
the custom converter will be used rather than the converter generated
by the InstAlias.

This patch adds the UseInstAsmMatchConverter field to the InstAlias
class, which allows you to override this behavior and force the
converter generated by the InstAlias to be used.

This is required for some future improvemnts to the R600 assembler.

d714fcf5c8 Use std::bitset for SubtargetFeatures.
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures.
Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables. 
This should now be fixed.

The v1i128 type is needed for the quadword add/substract instructions introduced
in POWER8. Futhermore, the PowerPC ABI specifies that parameters of type v1i128
are to be passed in a single vector register, while parameters of type i128 are
passed in pairs of GPRs. Thus, it is necessary to be able to differentiate
between v1i128 and i128 in LLVM.

If the 1st predicate is not an AssemblerPredicate, while the 2nd one is, nothing gets emitted for the 1st one, but we still emit the '&&' because of the 2nd predicate.
This generated code looks like "( && Cond2)" and is invalid.

f09378397e [MCInstPrinter] Enable MCInstPrinter to change its behavior based on the
per-function subtarget.

Currently, code-gen passes the default or generic subtarget to the constructors
of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which
enables some targets (AArch64, ARM, and X86) to change their instprinter's
behavior based on the subtarget feature bits. Since the backend can now use
different subtargets for each function, instprinter has to be changed to use the
per-function subtarget rather than the default subtarget.

This patch takes the first step towards enabling instprinter to change its
behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to
AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the
various print methods table-gen auto-generates. 

I will follow up with changes to instprinters of AArch64, ARM, and X86.

765aab84d6 Revert "Use std::bitset for SubtargetFeatures"
This reverts commit r233055.

It still causes buildbot failures (gcc running out of memory on several platforms, and a self-host failure on arm), although less than the previous time.

d3ab717935 Use std::bitset for SubtargetFeatures
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first time this was committed (r229831), it caused several buildbot failures. 
At least some of the ARM ones were due to gcc/binutils issues, and should now be fixed.
