I can confirm the gentoo-sources experimental gcc-opts patch works fine on git-sources 5.6.0-rc1.
gentoo-audio /usr/src/linux-5.6-rc1 # patch -p1 < 5012_enable-cpu-optimizations-for-gcc91.patch
patching file arch/x86/include/asm/module.h
patching file arch/x86/Kconfig.cpu
patching file arch/x86/Makefile
patching file arch/x86/Makefile_32.cpu
gentoo-audio /usr/src/linux-5.6-rc1 #

I copy pasted starting at the lines:
--- a/arch/x86/include/asm/module.h 2019-12-15 18:16:08.000000000 -0500
+++ b/arch/x86/include/asm/module.h 2019-12-17 14:03:55.968871551 -0500
and including all the following lines into a text file, naming it "5012_enable-cpu-optimizations-for-gcc91.patch" (no quotes)
Then put it in the kernel source directory, and ran
patch -p1 < 5012_enable-cpu-optimizations-for-gcc91.patch
Then ran make xconfig, loaded my system specific kernel config for 5.5.2, and set the kernel processor gcc opts for "native." Saved the edited config to file the source directory, and it complied fine on my newly upgraded Ryzen 7 3700x system. :)

Booted normally, system running normally.
