This revison lifts the artificial restriction on having exact matches between source and destination type shapes. A static size may become dynamic. We still reject changing a dynamic size into a static size to avoid the need for a runtime "assert" on the conversion. This revision also refactors some of the conversion code to share same-content buffers. Reviewed By: bixia Differential Revision: https://reviews.llvm.org/D111915
