Some improvements to code display

[Keluaa]

SASS:

• option to remove ; Location comments
• too many mangled names, can we unmangle them? can we simplify them?

PTX:

• { blocks } are not indented
• same problem with mangled names
• calls are quite unreadable and unrecognizable at a quick glance:

	call.uni 
	throw_boundserror, 
	(
	param0
	);

LLVM IR:

• again, mangled names

Julia IR:

• This CUDA code has some nasty "inline modules" lines, what can we do about them?

using KernelAbstractions
@kernel function test_ka(a, b, c)
           i = @index(Global, Linear)
           s = @localmem eltype(a) 100
           l = @private eltype(a) 3
           s[i] = a[i]
           @synchronize()
           l[1] = mod1(i * 42, 100)
           l[2] = mod1(i * 46, 100)
           l[3] = mod1(abs(Int(c[i])) * 465, 100)
           a[i] = b[i] * c[i] - s[mod1(i + 42, 100)]
           b[i] = c[i] - a[i] + s[mod1(i + 27, 100)]
           c[i] = b[i] * a[i] * s[mod1(i + 37, 100)]
end
a = CUDA.rand(Int64, 100); b = CUDA.rand(Int64, 100); c = CUDA.rand(Int64, 100);
@code_for type=:cuda_typed debuginfo=:none test_ka(CUDABackend(), 100)(a, b, c; ndrange=size(a))

In general:

• The debuginfo=:none option is quite useful for LLVM IR and typed Julia IR, but all other types are unsupported, so you must remove/add it every time. Having a generic option to enable "less debug info" (and shorter than debuginfo=:none) would be good
