* [TF][Relay][Op] Pass module when infer shape

* Fix lint

* Improve style

* Add test

Previously runtime::Module was supported using shared_ptr.
This PR refactors the codebase to use the Object protocol.

It will open doors to allow easier interpolation between
Object containers and module in the future.

the test case was removed in #4181 for some reason

LLVM 8 will crash when loading the bitcodes

This is a runtime check as the file will be compiled in even when
USE_ROCM OFF is used in the configuration if ROCM is installed
in the default location.

Fixes: #4087

* Add StopGradient. Add batch_dims attr to ignore list for GatherV2

* Trigger CI

* [VTA] Performance optimize, remove unnecessary contigious memory use.

Issue:
Uop maintain a cache vector to copy uop data into contigious DRAM memory for
FPGA/Simulator use, but this cache vector not get clear after FPGA/Simulator
core run, in Resnet18 case, if we printf the cache size in UopQueue::ReadBarrier
function, we can saw such cache size keep increase, this would cause
no use data copy and unnecessary contigous DRAM memory malloc.

Analysis:
This issue caused by not clear cache_ vector when do
uop_queue_.Reset().

Solution:
Override BaseQueue Reset function in UopQueue and add cache_ clear
logic.

* address review comments, remove spacing.

* Support reshape for dynamic shape in tf converter

* Only allow reshape directly after shape function for symbolic input shape

* Fix lint

* [NODE][REFACTOR] Rename IRFunctor->NodeFunctor, use function pointer for dispatching.

Previously we used std::function for the functor dispatching.
It introduces additional overhead and problems during dll destruction(of std::function).

This PR changes the std::function to function pointers.
This change a bit restrictions around the set_dispatch that we can get around,
but will improve the general efficiency by reducing one level of indirection in the std::function.
We also no longer need special marcos to register functions to the Functor.
