[PATCH] MATCH: Add pattern for `signbit(x) ? x : -x` into abs (and swapped)

This adds a simple pattern to match.pd for `signbit(x) ? x : -x` into abs. This can be done for all types even ones that honor signed zeros and NaNs because both signbit and - are considered only looking at/touching the sign bit of those types and does not trap either. OK? Bootstrapped and tested

[PATCH v3] Machine_Mode: Extend machine_mode from 8 to 16 bits

From: Pan Li We are running out of the machine_mode(8 bits) in RISC-V backend. Thus we would like to extend the machine_mode bit size from 8 to 16 bits. However, it is sensitive to extend the memory size in common structure like tree or rtx. This patch would like to extend the machine_mode bits t

RE: [PATCH] Machine_Mode: Extend machine_mode from 8 to 16 bits

Oops, looks missed this part when I search all machine_mode by word. Thanks kito for catching this. It seems there is no easy way to remind the developer to change (for example 16 to 32 bits) the below part in future, how about add some comments to MACHINE_MODE_BITSIZE for this? Pan -Orig
