From: Abhishek Dubey <adubey@linux.ibm.com>

The first 2 patch enable support for instruction array. Now, the 
instruction offset map maintain the mapping:
original inst -> xlated inst -> jited inst

The last two patch enable support for indirect jump. Any eligile
register can store jump target address for control flow to jump.

The features will be enabled on ppc32 in a separate series.

The patch series is rebased over:
https://lore.kernel.org/bpf/20260226031324.17352-1-adubey@linux.ibm.com

All selftest related to instruction array and indirect jump
are passing.
