This change adds support for RV32GC RISCV binaries. Specifically, it:
* Updates the return matcher to recognize returns in 32-bit binaries
* Updates detection of unsupported binaries to allow RV32GC binaries
* Adds RV32GC versions of the RV64GC tests
* riscv: added grift as submodule
* added macaw-riscv project
* make arch polykinded everywhere in macaw base
* stubbed out riscv_info
* update grift
* started on RISCVReg
* started on RISCVReg
* RegisterInfo instance for RISCVReg (a few unimplemented fields)
* filled out archRegSet
* filled out withArchConstraints, archAddrWidth, and archEndianness
* added Arch module
* RISCV initialBlockRegs
* preliminary work on disassembleFn
* wip: disassembleFn
* made things more lens-y
* wip: disassemble instruction
* finished disassembly of grift assignment statements
* separated out DisInstM into separate module
* disassembly wip
* finished disassembleBlock
* Finished riscvDisassembleFn
* bump grift submodule
* made macaw discovery poly-kinded
* added risc-v test suite
* added risc-v test suite
* fixed macaw semantics to hardware x0 to constant value 0
* added riscvPreserveReg based on assembler's manual
* riscvDemandContext
* successfully disassembled a block!
* enhanced tests to allow optional entry point spec
* stubbed out identifyCall
* stubbed out identifyReturn
* passing initial test
* added checkForReturnAddr stub
* fleshed out identifyCall and identifyReturn
* update grift submodule
* bug fix and exception handling
* added EXC register, which tracks whether or not we've attempted to
read from/write to any system registers.
* Replaced custom CSR type with GRIFT's (but we're not using it
currently)
* added better show instance for GPRs we should migrate this to a
GRIFT pretty printer at some point)
* Fixed a vicious bug in the semantics; unsigned and signed LT were
getting swapped in translation
* added pattern synonyms for GPRs
* improved docs and fixed RISCVReg bug (GP was 3 instead of 4)
* changed undefineds to errors
* changed RISCV class to RISCVConstraints
* wrapped GRIFT's "RV" parameter in a type to remove the need to make
macaw architecture parameter polykinded
* rolled back all changes to macaw base that made things poly-kinded
* reverted two more macaw core changes, updated license, removed old PPC test
* macaw: update to upstream changes in bv-sized and grift
* address code review comments
* macaw-riscv: expose fewer modules
* Update RISCVTermStmt definition
* Update riscv_info. macaw-riscv now builds against master
* Update bv-sized and cabal freeze files
* Update cabal freeze files with satisfying lens version
* Get tests building
* Fix printf runtime error
* Add simpler tests
* Change RISCV target version and update grift pointer
[skip ci]
* Compressed branch test passes
[skip ci]
* Add additional small tests
[skip ci]
* Introduce a syscall PrimFn
* Syscalls now correctly classified
* Fix return regs from syscall
* Extract syscall arguments
* Update expected riscv test results
* Add macaw-riscv build + test to CI
* Get building with GHC 9.0.2
* Revert "Update cabal freeze files with satisfying lens version"
This reverts commit 4aa95c19c3.
* Install softfloat in CI
* Update Grift
* Some initial cleanup
* More cleanup
* Resolve FIXME on getReg
* Detect and only accept rv64gc rvreprs
* Address Tristan's PR comments
* Update Grift pointer
* Add info on installing Softfloat to README for macaw-riscv
* Add missing submodule step to softfloat build instructions

The previous commits were valid, but github requires Travis builds to
complete successfully before allowing a merge to master. The Travis
builds did complete, but somehow the communication between Travis and
Github failed, so Github still is waiting for the Travis build.
Pushing this minor change to re-trigger Travis builds so that this
branch can be merged to master.
To avoid conflicting stack.yaml files when crucible is used a
submodule in another repo with a top level stack.yaml.
Also, update the README to include creating a stack.yaml symlink
before building with stack the first time.
