fc7b5d8c6a Mem model spv 1.4 (#2565)
* Update memory model support for SPIR-V 1.4

Fixes #2552

* Upgrade memory model now supports two memory access operands for
OpCopyMemory*
  * in all cases the pass will first generate two operands by either
  adding them or copying
  * updates accounts for multiple operands
  * tests

Upgrade modf and frexp (#2266)
Fixes #2138

* Modf and frexp are upgraded to use the struct version of the
instruction and generate an explicit store whose flags can be upgraded
separately
* Fixed major bug where availability and visibility were reversed for
non-copy memory instructions
* Fixed bug where availability and visibility scope operands were reversed for copy memory
* Upgraded all opt tests to use SPV_ENV_UNIVERSAL_1_3
* Upgrade tests moved into unified tests and removed standalone test
