If the shader does not specify "core" or "compatibility" in shaders
above 1.40 we were defaulting these shaders to core shaders when
in a compat profile. Instead default to compat shaders.
This brings us inline with the behaviour of the binary drivers and
fixes a crash on start-up for the game Foundation.

at the beginning of the buffer to determine where to write, then dumps
the args after that.

SPIR-V modules can have multiple shaders (including of the same
stage), but the global variables are all declared for the whole
module. This can result in variables with same Binding but
incompatible types, so those need to be removed before we use.
Previously, a similar issue but with a narrower scope was fixed by
6775665e5e ("spirv: Eliminate dead input/output variables after
translation.").
This patch depends on the previous patch that prevents variables used
only in pointer initializers to be considered dead.

With the block's end_ip accidentally being the ip of the next instruction,
contrary to the comment, you would end up doing end-of-block freeing early
and have the value missing when it came time to emit the next instruction.
Just expand the ips to have separate ones for start and end of block --
while it means that nir_instr->index is no longer incremented by 1 per
instruction, it makes sense for use in liveness because a backend is
likely to need to do other things at block boundaries (like emit the if
statement's code), and having an ip to identify that stuff is useful.
