2020-11-05[SVE] Return StackOffset for TargetFrameLowering::getFrameIndexReference.Sander de Smalen
To accommodate frame layouts that have both fixed and scalable objects on the stack, describing a stack location or offset using a pointer + uint64_t is not sufficient. For this reason, we've introduced the StackOffset class, which models both the fixed- and scalable sized offsets. The TargetFrameLowering::getFrameIndexReference is made to return a StackOffset, so that this can be used in other interfaces, such as to eliminate frame indices in PEI or to emit Debug locations for variables on the stack. This patch is purely mechanical and doesn't change the behaviour of how the result of this function is used for fixed-sized offsets. The patch adds various checks to assert that the offset has no scalable component, as frame offsets with a scalable component are not yet supported in various places.

2020-08-22[LiveDebugValues] Install an implementation-picking LiveDebugValues passJeremy Morse
This patch renames the current LiveDebugValues class to "VarLocBasedLDV" and removes the pass-registration code from it. It creates a separate LiveDebugValues class that deals with pass registration and management, that calls through to VarLocBasedLDV::ExtendRanges when runOnMachineFunction is called. This is done through the "LDVImpl" abstract class, so that a future patch can install the new instruction-referencing LiveDebugValues implementation and have it picked at runtime. No functional change is intended, just shuffling responsibilities. Differential Revision: https://reviews.llvm.org/D83046

This is a pure file move of LiveDebugValues.cpp ahead of the pass being refactored, with an experimental new implementation to follow.
