5507c2bf35 tcg: Introduce atomic helpers for integer min/max
Given that this atomic operation will be used by both risc-v
and aarch64, let's not duplicate code across the two targets.

22fc352703 tcg: Add generic vector helpers with a scalar operand
Use dup to convert a non-constant scalar to a third vector.

Add addition, multiplication, and logical operations with an immediate.
Add addition, subtraction, multiplication, and logical operations with
a non-constant scalar.  Allow for the front-end to build operations in
which the scalar operand comes first.

f49b12c6e6 tcg: Add generic helpers for saturating arithmetic
No vector ops as yet.  SSE only has direct support for 8- and 16-bit
saturation; handling 32- and 64-bit saturation is much more expensive.

d0ec97967f tcg: Add generic vector ops for constant shifts
Opcodes are added for scalar and vector shifts, but considering the
varied semantics of these do not expose them to the front ends.  Do
go ahead and provide them in case they are needed for backend expansion.

7f11636dbe tcg: remove addr argument from lookup_tb_ptr
It is unlikely that we will ever want to call this helper passing
an argument other than the current PC. So just remove the argument,
and use the pc we already get from cpu_get_tb_cpu_state.

This change paves the way to having a common "tb_lookup" function.
