Due to mapping changes, we now rarely place the code_gen_buffer
near the main executable. Which means that direct calls will
now rarely be in range.
So, always use indirect calls for tail calls, which allows us to
avoid clobbering %o7, and therefore we need not save and restore it.

Changes from v5:
* Use tcg_out_movi_imm13 from tcg_out_addsub2_i64.
* Split out tcg_out_movi_imm32 to avoid recursion.
* Reinstate the assert vs TCG_REG_T2 in tcg_out_movi.

* Remove assert from tcg_out_movi; rely on the one in tcg_out_movi_int (pmm).

Recent Linux versions added support to read ID_AA64ISAR2_EL1. On M1,
those reads trap into QEMU which handles them as faults.
However, AArch64 ID registers should always read as RES0. Let's
