Summary:
Useful in case you want to have control over interrupt vector generation.
For example in Rust language we have an arrangement where all unhandled
ISR vectors gets mapped to a single default handler function. Which is
hard to implement when LLVM tries to generate vectors on its own.

This is LLVM part of D56663
Linker scripts shipped by TI require to have every
interrupt vector in a separate section with a specific name:
SECTIONS
{
__interrupt_vector_XX : { KEEP (*(__interrupt_vector_XX )) } > VECTXX
...
}
Follow the requirement emit the section for every vector
which contain address of interrupt handler:
.section __interrupt_vector_XX,"ax",@progbits
.word %isr%
