feat: support inst lifetime trace (#4007)
PerfCCT(performance counter commit trace) is a Instruction-level granularity perfCounter like GEM5 How to use this: 1. Make with "WITH_CHISELDB=1" argument 2. Run with "--dump-db --dump-select-db lifetime", then get the database 3. Instruction lifetime visualize run "python3 scripts/perfcct.py "the-db-file-path" -p 1 -v | less" 4. Analysis script now is in XS-GEM5 repo, see https://github.com/OpenXiangShan/GEM5/blob/xs-dev/util/ClockAnalysis.py
How it works: 1. Allocate one unique tag "seqNum" like GEM5 for each instruction at fetch stage 2. Passing the "seqNum" in each pipeline 3. Recording perf data through the DPIC interface

fix(exception): check high address bits of jump target (#3003)
This commit contains high address bits checking of jump target. In previous implementation, we simply truncated the higher bits of jump target address, which made it impossible to raise exceptions in such cases.
To resolve this problem, we detect the invalid jump target in jump/branch/CSR and, this information to frontend and store the complete invalid target in a single register in backend. The frontend will then raise an exception to backend and backend will also use the invalid target in the register to write xtval and mepc.
