Takoroka fe5cb5efdf nx2: title 4's intro cutscene renders correctly
Native shader capture counted CALL.REL.NOINC as a function call, so a program
using it waited for a RET after its EXIT and read on into the following
shaders until a garbage branch target made it fail. NOINC calls push no
return address (the compiler uses them as jumps; the lowering already treats
them so): count them as forward branches.

That shader builds title 4's 3D colour-grading LUT once per scene; with it
rejected the LUT stayed empty and the tonemap turned every frame black. The
intro cutscene now renders lit and graded, with subtitles, through the
bilinear stand-in for the tensor-core upscaler.

Also: rejected captures dump to EDEN_NX2_SHADER_DUMP as rejected-<addr>.bin
and report the offending instruction.
