Replaces direct calls to eh-frame registration with calls to methods on an

This is split out from my patches to split register allocation into a
separate SGPR and VGPR phase, and has some parts that aren't yet used
(like maintaining LiveIntervals).
This simplifies making the frame pointer register callee saved. As it
is now, the code to determine callee saves needs to predict all the
possible SGPR spills and how many callee saved VGPRs are needed. By
handling this before PrologEpilogInserter, it's possible to just check
the spill objects that already exist.

If the block being cloned contains a PHI node, in general, we need to
clone that PHI node, even though it's trivial. If the operand of the PHI
is an instruction in the block being cloned, the correct value for the
operand doesn't exist until SSAUpdater constructs it.
We usually don't hit this issue because we try to avoid threading across
loop headers, but it's possible to hit this in some cases involving
irreducible CFGs. I added a flag to allow threading across loop headers
to make the testcase easier to understand.
Thanks to Brian Rzycki for reducing the testcase.

This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.
This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.
Since Bitcode uses Core for the IR part:
libLLVMRemarks -> Bitcode -> Core
and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):
Core -> libLLVMRemarks
we need to separate the Bitstream and Bitcode part.
For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.

Per feedback in D64115, simplify the test.
`hidden` is left in though, because every test in the file has it.

Summary:
Adds `--passive-segments` and `--active-segments` flags to control
what kind of segments are emitted. For now the default is always
to emit active segments so this is not a breaking change, but in
the future the default will be changed to passive segments when
shared memory is requested and active segments otherwise. When
passive segments are emitted, corresponding memory.init and
data.drop instructions are emitted in a `__wasm_init_memory`
function that is automatically called at the beginning of
`__wasm_call_ctors`.

Precedence was wrong in an assert added in r364961. Add braces around the
assertion condition to make it right.
See: https://reviews.llvm.org/D64084
llvm-svn: 365069
The motivation for this is two fold:
1) Make the output (and thus tests) a bit more readable to a human trying to understand the result of the transform
2) Reduce spurious diffs in a potential future change to restructure all of this logic to use SCEVExpander (which hoists by default)

Instead of just stopping to see if we have a G_CONSTANT, instead, look through
G_TRUNCs, G_SEXTs, and G_ZEXTs.

This patch adjusts tests not to depend on deprecated FileCheck
behavior that permits overlapping matches within a block of
`CHECK-DAG` directives:
1. `thinlto-function-summary-originalnames.ll`: The directive with the
pattern `<COMBINED` is surely intended to match `<COMBINED ` (note the
trailing space), but it instead matches
`<COMBINED_GLOBALVAR_INIT_REFS`, for which there is a separate
directive. With the deprecated behavior, both directives match the
latter text and neither match the former text. I've adjusted the
former directive so it matches only the former text.
2. `thinlto-summary-local-5.0.ll`: Two directives have identical
patterns when they were clearly meant to have different patterns.
3. `upgrade-pointer-address-space.ll`: There are three identical
directives but only two occurrences of the matching text. With the
deprecated behavior, they always match exactly the same text, so the
behavior can't have been useful. I removed one of the directives and
converted the other two from `CHECK-DAG` to `CHECK`.

We previously marked all the tests with branch funnels as
`-verify-machineinstrs=0`.
This is an attempt to fix it.
1) `ICALL_BRANCH_FUNNEL` has no defs. Mark it as `let OutOperandList =
(outs)`
2) After that we hit an assert: ``` Assertion failed: (Op.getValueType()
!= MVT::Other && Op.getValueType() != MVT::Glue && "Chain and glue
operands should occur at end of operand list!"), function AddOperand,
file
/Users/francisvm/llvm/llvm/lib/CodeGen/SelectionDAG/InstrEmitter.cpp,
line 461. ```
The chain operand was added at the beginning of the operand list. Move
that to the end.
3) After that we hit another verifier issue in the pseudo expansion
where the registers used in the cmps and jmps are not added to the
livein lists. Add the `EFLAGS` to all the new MBBs that we create.

We haven't changed the set of users, just specialized an operand for those users. Given that, the previous wrap flags must still be correct.
Sorry for the lack of test case. Noticed this while working on something else, and haven't figured out to exercise this standalone.

Summary:
This diff improve the capability of DAGCOmbine to generate linear carries propagation in presence of a diamond pattern. It is now able to match a large variety of different patterns rather than some hardcoded one.
Arguably, the codegen in test cases is not better, but this is to be expected. The goal of this transformation is more about canonicalisation than actual optimisation.
