Propose an extension to base type DIEs such that DW_ATE_address-encoded
base types can include an architecture specific address space. Use this
to implement DW_OP_convert conversions between AMDGPU address space
addresses where meaningful.
Summary:
Add description to AMDGPUDwarfExtensionsForHeterogeneousDebugging.rst
for "DWARF Operations to Create Vector Composite Location Descriptions"
proposal to explain the main motivation is to facilitate more compact
DWARF that is faster to evaluate.

Subscribers:
Repurpose the DW_OP_LLVM_aspace_implicit_pointer encoding (0xe9) as the
encoding for a new operation DW_OP_LLVM_user which prefixes all other
new operations.

2. Allow different call frames to be associated with different target
architectures in a single thread.

Update DWARF Extensions For Heterogeneous Debugging proposal for the
DW_OP_LLVM_overlay operation:
1. Add an example.
2. Correct typo in definition of rbss.
3. Correct definition to specify both operands of the

- Add current iteration to the context of a DWARF expression evaluation.
- Add DW_AT_LLVM_iterations attribute to specify the number of
iterations executing concurrently.
- Add DF_OP_LLVM_push_iteration to support optimizations that result in
multiple iterations executing concurrently.
- Add DW_OP_LLVM_overlay and DW_OP_LLVM_bit_overlay to support
expressing the location of arrays that are promoted to vector
registers in SIMD vectorized loops.
- Generally clarify the difference between SIMT and SIMD execution.
- Change the DW_AT_LLVM_active_lane attribute to take location
description expression so that a loclist can be used to express
different vales at different program locations.
