[AMDGPU][GFX11] buffer_load_lds_{size} instructions do not exist (#132916) 
According to the shader manual there are not buffer load lds
instructions of gfx11.

The tests for the regular `buffer_load ... lds` instructions for gfx11
are already present in AMDGPU/gfx11_asm_mubuf.s, where the compiler
fails to encode the instructions for this target.

[AMDGPU][docs][NFC] Replace gfx940 with gfx942 in the gfx940 ISA doc (#126906) 
gfx940 and gfx941 are no longer supported. This is the last one of a
series of PRs to remove them from the code base.

The ISA documentation still contains a lot of links and file names with
the "gfx940" identifier. Changing them to "gfx942" is probably not worth
the cost of breaking all URLs to these pages that users might have saved
in the past.

For SWDEV-512631
