Delete tests with invalid SPIR-V inputs

The structured CFG rule was revised/clarified in SPIR-V 1.6 Rev2
Validation now rejects a few cases.

SpvParserTest, ValueFromBlockNotInBlockOrder
SpvParserFunctionVarTest, EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
SpvParserFunctionVarTest_EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
  - Originally from crbug.com/tint/804
    Invalid by SPIR-V 1.6 Rev2 update to validation rules:
     - Block 80 is a structurally reachable continue target
     - Block 25 is not structually reachable, and not part of the loop,
       but branches to 80.

vk-gl-cts/graphicsfuzz/cov-dead-branch-func-return-arg/0-opt.*
  -  The continue construct with the continue target 37[%37]
     is not structurally post dominated by the back-edge block 64[%64]
  - The SPIRV-Tools inliner no longer creates such cases.  It splits the
    single-block loop and pushes the continue target down.

vk-gl-cts/graphicsfuzz/nested-for-loops-with-return/0-opt.spvasm
  - The loop headed at block 46 does not structurally dominate its merge
    block 44.  There is a continue-target edge from 41 to 44.

SpvParserCFGTest_EmitBody_Loop_MultiBlockContinueIsEntireLoop.spvasm
SpvParserCFGTest_LabelControlFlowConstructs_MultiBlockLoop_HeaderIsContinue.spvasm
SpvParserCFGTest_SiblingLoopConstruct_ContinueIsWholeMultiBlockLoop.spvasm
SpvParserCFGTest, ClassifyCFGEdges_BackEdge_MultiBlockLoop_MultiBlockContinueConstruct_ContinueIsHeader
SpvParserCFGTest, EmitBody_Loop_MultiBlockContinueIsEntireLoop
SpvParserCFGTest, LabelControlFlowConstructs_MultiBlockLoop_HeaderIsContinue
SpvParserCFGTest, SiblingLoopConstruct_ContinueIsWholeMultiBlockLoop
 - Continue target 20 also its own loop header, but is not structurally
   post-dominated by the backedge block.
 - Delete the end-to-end test.
 - Keep the unit test because it's about classifying edges, but disable dumping
   into the end2end suites.
