7349eab099 Merge pull request #136 from dekimir/no-block-removal 
SPV: Don't remove SPIR-V blocks before codegen, use new InReadableOrder instead.

ed55bcd9f8 Don't remove SPIR-V blocks before codegen. 
A removed block releases its instructions, so Module::idToInstruction
suddenly contains dangling references.  The original motivation for
block removal was to skip some unreachable blocks, but that's already
achieved by InReadableOrder.cpp.

Also updated stale comments.

38d039d063 Rework inReadableOrder() as a recursive descent. 
Add a test for unreachable merge block.

removing unreachable ones.

c57b2a97fa Memory/Perf: For link-mode, isolate file I/O so API can be looped over. 
Separating file I/O from compile/link lets the compile/link be done
repeatedly in a loop for testing and measuring of performance and
memory footprint, including seeing memory growth over time for
functional-level memory-leak testing.

While the older compile-only mode already had this functionality,
and typically showed no memory leaks, SPIR-V uses the link path,
has pending "TODO" for memory freeing, and this shows several
kilobytes of leaking per compile-link. Most likely, pending
merge request 131 will address much of this.

a76766a434 getBaseAlignment: Use the rowMajor argument for determining matrix strides 
The argument version is passed in from above and struct handling ensures
that row-majorness gets propagated correctly from one level to the next.
If we just look at the type itself and it's embedded in a struct that's
declared row-major, we may get the wrong stride.

832c65c33b Fix back-branch target for do-while loops. 
To ensure back branches always go to a header block, create a header
block even for !testFirst loops.  Then unify common code between the
testFirst/!testFirst cases.

Generate the header-block code first, so update golden files.

Realize that certain infinite loops generate invalid SPIR-V, so put a
TODO to instead abort code generation in such cases.
