Revert "Temporarily Revert "[gicombiner] Add the MatchDag structure and parse instruction DAG's from the input""
This reverts commit e62e760f29567fe0841af870c65a4f8ef685d217.
The issue @uweigand raised should have been fixed by iterating over the
vector that owns the operand list data instead of the FoldingSet.
The MSVC issue raised by @thakis should have been fixed by relaxing the
regexes a little. I don't have a Windows machine available to test that so
I tested it by using `perl -p -e 's/0x([0-9a-f]+)/\U\1\E/g' to convert the
output of %p to the windows style.
I've guessed at the issue @phosek raised as there wasn't enough information
to investigate it. What I think is happening on that bot is the -debug
option isn't available because the second stage build is a release build.
I'm not sure why other release-mode bots didn't report it though.

[gicombiner] Add the MatchDag structure and parse instruction DAG's from the input
Summary:
The MatchDag structure is a representation of the checks that need to be
performed and the dependencies that limit when they can happen.
There are two kinds of node in the MatchDag:
* Instrs - Represent a MachineInstr
* Predicates - Represent a check that needs to be performed (i.e. opcode, is register, same machine operand, etc.)
and two kinds of edges:
* (Traversal) Edges - Represent a register that can be traversed to find one instr from another
* Predicate Dependency Edges - Indicate that a predicate requires a piece of information to be tested.
For example, the matcher:
(match (MOV $t, $s),
(MOV $d, $t))
with MOV declared as an instruction of the form:
%dst = MOV %src1
becomes the following MatchDag with the following instruction nodes:
__anon0_0 // $t=getOperand(0), $s=getOperand(1)
__anon0_1 // $d=getOperand(0), $t=getOperand(1)
traversal edges:
__anon0_1[src1] --[t]--> __anon0_0[dst]
predicate nodes:
<<$mi.getOpcode() == MOV>>:$__anonpred0_2
<<$mi.getOpcode() == MOV>>:$__anonpred0_3
and predicate dependencies:
__anon0_0 ==> __anonpred0_2[mi]
__anon0_0 ==> __anonpred0_3[mi]
The result of this parse is currently unused but can be tested
using -gicombiner-stop-after-parse as done in parse-match-pattern.td. The
dump for testing includes a graphviz format dump to allow the rule to be
viewed visually.
Later on, these MatchDag's will be used to generate code and to build an
efficient decision tree.
