[AArch64] Improve TLS Descriptor pattern to release RTL loop IV opt

The instruction sequences for preparing argument for TLS descriptor
runtime resolver and the later function call to resolver can actually be
hoisted out of the loop.

Currently we can't because we have exposed the hard register X0 as
destination of "set".  While GCC's RTL data flow infrastructure will
skip or do very conservative assumption when hard register involved in
and thus some loop IV opportunities are missed.

This patch add another "tlsdesc_small_pseudo_<mode>" pattern, and avoid
expose x0 to gcc generic code.

Generally, we define a new register class FIXED_R0 which only contains register
0, so the instruction sequences generated from the new add pattern is the same
as tlsdesc_small_<mode>, while the operand 0 is wrapped as pseudo register that
RTL IV opt can handle it.

Ideally, we should allow operand 0 to be any pseudo register, but then
we can't model the override of x0 caused by the function call which is
hidded by the UNSPEC.

So here, we restricting operand 0 to be x0, the override of x0 can be
reflected to the gcc.

compiler: Use context to determine types of complex expressions.

    When determining the type of a complex expression, it is important
    to recognize cases where a complex value can be represented as a
    real number.

    Fixes golang/go#11572.
