Vyacheslav Levytskyy 4f403e88f2 [SPIR-V] Ensure that OpExtInst instructions generated by NonSemantic_Shader_DebugInfo_100 are not mixed up with other OpExtInst instructions (#107007)
This PR is to ensure that OpExtInst instructions generated by
NonSemantic_Shader_DebugInfo_100 are not mixed up with other OpExtInst
instructions.

Original implementation
(https://github.com/llvm/llvm-project/pull/97558) has introduced an
issue by moving OpExtInst instruction with the 3rd operand equal to
DebugSource (value 35) or DebugCompilationUnit (value 1) even if
OpExtInst is not generated by NonSemantic_Shader_DebugInfo_100
implementation code.

The reproducer is attached as a new test case. The code of the test case
reproduces the issue, because "lgamma" has the same code (35) inside
OpenCL_std as DebugSource inside NonSemantic_Shader_DebugInfo_100.
