itself. For example, VADD.I16 q0, q1, q2 is a neon instruction that operates on 16-bit integer
elements stored in 128-bit Q registers, which leads to eight 16-bit lanes in parallel. This kind
of information impacts how the instruction takes to execute and what dependencies this may cause.
On RISCV however, the data that impacts scheduling is encoded in CSR registers such as vtype or
vl, in addition with the instruction itself. But MCA does not track or use the data in these
registers. This patch fixes this problem by introducing Instruments into MCA.

[lldb-vscode] Send Selected Statistics Dump in Terminated Event
This patch will gather debug info & breakpoint info from the statistics dump (from `(SBTarget.GetStatistics())` func) and send to DAP in terminated event.
The statistics content can be huge (especially the `modules`) and dumping in full JSON can create delay in the IDE's debugging UI. (For more details, please read: https://github.com/llvm/llvm-project/commit/
7bbd0fba986c241162b77b7e424ad82bc7e17b41 ). Hence, we will filter out large contents before returning it in terminated event.
It will keep all the metadata fields (those starts with "total"). For large contents, it uses the opt-out strategy. Currently it only removes the "modules" field. This way every time a new top-level field being added, we will be able to capture them from DAP log without changing lldb-vscode.
The DAP terminated event should look like
```
{
"event":"terminated",
"seq":0,
"statistics": {
"memory": <JSON string>
"targets": <JSON string>, // it's a JSON array, breakpoints info included in each target
<metadata_key: value> // pairs
},
"type":"event"
}
```
All the info above will be append to statistics field in the terminated event
Test Plan
Debugged a simple hello world program from VSCode. Exit debug session in two ways: 1) run to program exit; 2) user initiated debug session end (quit debugging before program exit).
Check DAP log and see both debug sessions have statistics returned in terminated event.
Here's an example when debugging the test program:
```
{"event":"terminated","seq":0,"statistics":{"memory":"{\"strings\":{\"bytesTotal\":1843200,\"bytesUnused\":897741,\"bytesUsed\":945459}}","targets":"[{\"breakpoints\":[{\"details\":{\"Breakpoint\":{\"BKPTOptions\":{\"AutoContinue\":false,\"ConditionText\":\"\",\"EnabledState\":true,\"IgnoreCount\":0,\"OneShotState\":false},\"BKPTResolver\":{\"Options\":{\"NameMask\":[56],\"Offset\":0,\"SkipPrologue\":true,\"SymbolNames\":[\"foo\"]},\"Type\":\"SymbolName\"},\"Hardware\":false,\"Names\":[\"vscode\"],\"SearchFilter\":{\"Options\":{},\"Type\":\"Unconstrained\"}}},\"id\":1,\"internal\":false,\"numLocations\":1,\"numResolvedLocations\":1,\"resolveTime\":0.002232},{\"details\":{\"Breakpoint\":{\"BKPTOptions\":{\"AutoContinue\":false,\"ConditionText\":\"\",\"EnabledState\":true,\"IgnoreCount\":0,\"OneShotState\":false},\"BKPTResolver\":{\"Options\":{\"Column\":0,\"Exact\":false,\"FileName\":\"/data/users/wanyi/llvm-sand/external/llvm-project/lldb/test/API/tools/lldb-vscode/terminated-event/main.cpp\",\"Inlines\":true,\"LineNumber\":5,\"Offset\":0,\"SkipPrologue\":true},\"Type\":\"FileAndLine\"},\"Hardware\":false,\"Names\":[\"vscode\"],\"SearchFilter\":{\"Options\":{},\"Type\":\"Unconstrained\"}}},\"id\":2,\"internal\":false,\"numLocations\":0,\"numResolvedLocations\":0,\"resolveTime\":0.

The purpose of this patch is to provide a way to register tool-provided callbacks into libomp when libomptarget is loaded.
Introduced a cmake variable LIBOMPTARGET_OMPT_SUPPORT that can be used to control OMPT target support. It follows host OMPT support, controlled by LIBOMP_HAVE_OMPT_SUPPORT.
Added a connector that can be used to communicate between OMPT implementations in libomp and libomptarget or libomptarget and a plugin.
Added a global constructor in libomptarget that uses the connector to force registration of tool-provided callbacks in libomp. A pair of init and fini functions are provided to libomp as part of the connect process which will be used to register the tool-provided callbacks in libomptarget.

Add FP8 E4M3 support to APFloat.
NVIDIA, ARM, and Intel recently introduced two new FP8 formats, as described in the paper: https://arxiv.org/abs/2209.05433. The first of the two FP8 dtypes, E5M2, was added in https://reviews.llvm.org/D133823. This change adds the second of the two: E4M3.
There is an RFC for adding the FP8 dtypes here: https://discourse.llvm.org/t/rfc-add-apfloat-and-mlir-type-support-for-fp8-e5m2/65279. I spoke with the RFC's author, Stella, and she gave me the go ahead to implement the E4M3 type. The name of the E4M3 type in APFloat is Float8E4M3FN, as discussed in the RFC. The "FN" means only Finite and NaN values are supported.
Unlike E5M2, E4M3 has different behavior from IEEE types in regards to Inf and NaN values. There are no Inf values, and NaN is represented when the exponent and mantissa bits are all 1s. To represent these differences in APFloat, I added an enum field, fltNonfiniteBehavior, to the fltSemantics struct. The possible enum values are IEEE754 and NanOnly. Only Float8E4M3FN has the NanOnly behavior.
After this change is submitted, I plan on adding the Float8E4M3FN type to MLIR, in the same way as E5M2 was added in https://reviews.llvm.org/D133823.
