Add SST integration into gpgpusim (#44)

* Add accommodations to run gpgpusim with SST simulation framework through balar

* Output setup_environment options when sourcing

* Add SST directive check when creating sim thread

* Add sst side test for jenkins

* sst-integration: update Jenkinsfile with offical sst-elements repo and fix bugs in pipeline script

* sst-integration: direct jenkins to rebuild gpgpusim before testing for sst

* sst-integration: fix bugs in sst repos config

* sst-integration: let Jenkins rebuilds simulator

Since the simulator needs to be configured with both normal mode and sst mode, need to rebuild make target to clean prior runs.

* sst-integration: Update Jenkinsfile to source env vars when running balar test

* sst-integration: refactor code to remove __SST__ flag

* sst-integration: fix a bug that init cluster twice for sst

* sst-integration: fix a bug of not sending mem packets to SST

* sst-integration: remove sst flags from makefiles and setup_env

* sst-integration: add comments to SST changes

* sst-integration: remove rebuilding simulator in jenkins when testing for SST

* sst-integration: revert simulator build script

* Add a function to support querying function argument info for SST

* sst-integration: add version detection for vanadis binary

* Automated Format

* add version detection support for gcc 10+

* sst-integration: add cudaMallocHost for SST

* sst-integration: fix a compilation bug

* sst-integration: add sst balar unittest CI

* sst-integration: specify GPU_ARCH for CI test

* sst-integration: use bash for github actions

* sst-integration: use https links for sst repos

* sst-integration: add SST dependencies to CI config

* sst-integration: remove sudo

* sst-integration: default to yes for apt install

* sst-integration: add manual trigger for github action

* sst-integration: remove wrong on event

* sst-integration: limit CPU usage for compilation

* sst-integration: fix wrong path

* sst-integration: use personal repo for testing

* sst-integration: remove sst-core source in CI to free space

* sst-integration: SST_Cycle use print stats with stream id

* Automated Format

* sst-integration: check for diskspace and try to clean it

* sst-integration: move out of docker image

* sst-integration: testing for ci path

* sst-integration: fix syntax

* sst-integration: pass env vars

* sst-integration: set env properly

* sst-integration: merge LLVM build and test into same job

* sst-integration: fix step order

* sst-integration: checkout correct branch for env-setup

* sst-integration: remove resourcing gpu apps

* sst-integration: revert back to docker github action

* sst-integration: enable debug trace for sst testing

* sst-integration: resourcing gpu app for env vars

* sst-integration: use GPUAPPS_ROOT for path for gpu app

* sst-integration: use GPUAPPS_ROOT for path for gpu app

* sst-integration: enable parallel ci tests and fix not returning with cudaMallocHostSST

* sst-integration: using debug flag for CI run

* sst-integration: revert debug ci run

* sst-integration: CI skips cuda sdk download and launch multiple jobs

* sst-integration: reenable parallel tests

* sst-integration: reduce concurrent test thread count

* sst-integration: skip long test for github runner

* sst-integration: try running CI with single core

* sst-integrtion: add callback to SST to check thread sync is done in SST_Cycle()

* sst-integration: ignore lookup if already found and add callbacks to SST

* Automated Format

* sst-integration: add support for indirect texture access

* Automated Format

* sste-integration: fix up for PR

* Automated Format
