Adding a VM bytecode disassembler and flags for tracing to stderr. (#7261)

Tracing is enabled by default in debug builds or with
`-DIREE_VM_EXECUTION_TRACING_ENABLE=1` for others. A flag can then be
passed to iree_vm_context_t to enable tracing for all invocations
(including initializers) or passed per-invocation to trace only individual
calls. `--trace_execution` was added to iree-check-* and iree-run-*, but
all other tools/API usage can set
`-DIREE_VM_EXECUTION_TRACING_FORCE_ENABLE=1` to force it on.

Source locations can be printed per traced line too, however they are
only practically usable with vm source listings as otherwise they are
big multiline fused locs or call sites from python. Until some more
refinement of location printing can be done they are disabled but can be
turned back on with `-DIREE_VM_EXECUTION_TRACING_SRC_LOC_ENABLE=1`.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.

Project Status

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!

Communication Channels

GitHub issues: Feature requests, bugs, and other work tracking
IREE Discord server: Daily development discussions with the core team and collaborators
iree-discuss email list: Announcements, general and low-priority discussion

Related Project Channels

MLIR topic within LLVM Discourse: IREE is enabled by and heavily relies on MLIR. IREE sometimes is referred to in certain MLIR discussions. Useful if you are also interested in MLIR evolution.
