[PATCH 03/11] alpha: allocate R_ALPHA_IRELATIVE

This patch introduces the R_ALPHA_IRELATIVE relocation type for the Alpha architecture, assigning it the value 42. This relocation is crucial for dynamic linking and static executables, as it allows the dynamic linker or C library startup code to execute an IFUNC’s resolver and store the returned address. The patch also adds the necessary entry to the BFD relocation map and defines the relocation’s class, preparing for linker support that will generate this relocation.
