Reid Kleckner 4af6025f09 [Hexagon] Remove unintended fallthrough from MC duplex code
I added these annotations in r345878 because I wasn't sure if the
fallthrough was intended. Krzysztof Parzyszek confirmed that they should
be breaks, so that's what this patch does.

Reid Kleckner bebc53f838 Annotate possibly unintended fallthroughs in Hexagon MC code, NFC
Clang's -Wimplicit-fallthrough check fires on these switch cases. GCC
does not warn when a case body that ends in a switch falls through to a
case label of an outer switch.

It's not clear if these fall throughs are truly intended.  The Hexagon
tests pass regardless of whether these case blocks fall through or
break.

For now, I have applied the intended fallthrough annotation macro with a
FIXME comment to unblock enabling the warning. I will send a follow-up
patch that converts them to breaks to the Hexagon maintainers.

Nicola Zaghen d34e60ca85 Rename DEBUG macro to LLVM_DEBUG.
The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
- Manual change to APInt
- Manually chage DOCS as regex doesn't match it.

In the transition period the DEBUG() macro is still present and aliased
to the LLVM_DEBUG() one.

Francis Visoiu Mistrih a8a83d150f [CodeGen] Use MachineOperand::print in the MIRPrinter for MO_Register.
Work towards the unification of MIR and debug output by refactoring the
interfaces.

For MachineOperand::print, keep a simple version that can be easily called
from `dump()`, and a more complex one which will be called from both the
MIRPrinter and MachineInstr::print.

Add extra checks inside MachineOperand for detached operands (operands
with getParent() == nullptr).

As part of the unification of the debug format and the MIR format,
always print registers as lowercase.

* Only debug printing is affected. It now follows MIR.

Colin LeMahieu fc52c11d80 [Hexagon] Adding functionality for duplexing. Duplexing is a way to compress commonly used pairs of instructions in order to reduce code size. The test case duplex.ll normally would be 8 bytes, assign register to 0 and jump to link register. After duplexing this is only 4 bytes. This also tests the HexagonMCShuffler code path which is used to make sure duplexed instructions still follow slot requirements.
