* Defined a common base class for TensorComputeOp and ComputeOp

* Made changes requested by @ZihengJiang

* added a testcase to assert that `tensorize` does not have any effect on TensorComputeOp ops.

* a preliminary version is done?

* we no longer need the redundant hybrid/api.py

* support assert stmt

* cast supported

* intrin -> runtime; util is mainly in charge of compilation time

* assert statement

* fix python lint

* fix cpp lint

* on the way to module

* rollback .cc

* fix typo, no direct expose then

* @vinx13 ceil is added i guess?

* wip...

* temp commit

* fix import

* i preliminary version is done?

* on the way to build hybrid module

* nearly fixed...

* resolve some review concerns

* support load/save

* fix lint

* thanks to xqdan fixed my typo

* fix build, make dump non-optional

* add vthread

* jesus why i added this

* [TVM][BUGFIX] Fix reductions in split axes

* A test case for the problem

* Fix the fix: skip loops that are related to reduction AND are unrelated to axis

* on the way to enable hybrid schedule

* I think I am done with imperfect loop split?

* copyright watermark

* loop annotation

* fix lint

* fix lint 1

* shit!

* loop reorder supported

* support bind to add some tests

* fused tested

* imperfect loop testcase

* fix lint

* add bind testcase

* fix doc

* fix online edit typo

* resolve @mercymercy review

* fix indent

* i should convince myself it is not flaky test first

* fix test hybrid

* how many flaky test are you expecting; i ball ball u to let me pass

* rebase halide...

[HYBRID FRONTEND] Modify hybrid script to new interface; hybrid op supported; enable compilation_database in CMakeList.txt (#1757)

* [IR] Change pragma scope convention, enable pass unroll option via pragma

* add coverage test

* add explicit unroll as option

* [PASS] StorageRewrite Fold Inplace op storage when possible

* update comment to fix typos

* when there is no intrin func, using body for initialization. For issue 714.

* Refine code per review comments, and add a test case.

* Fix lint issues.

During tensorize, call Simplify on algorithm and intrinsic definitions before CanonicalSimplify. This will prevent a number of false tensorize mismatches. (#718)

thanks, this we can use this solution for now
