[PATCH v2 4/4] xtensa: Improve constant synthesis for both integer and floating-point

This patch revises the previous implementation of constant synthesis. First, changed to use define_split machine description pattern and to run after reload pass, in order not to interfere some optimizations such as the loop invariant motion. Second, not only integer but floating-point is subjec
