HLSL gives no special meaning to the function named main. It does give special handling to entry points, and the active entry point when building a freestanding shader. Those cases are handled by the HLSLShader attribute, which can be implicitly applied to main if no other entry is specified, rather than the function name.

[HLSL] Treat main as any other function
c966c60 
HLSL doesn't distinguish `main` from any other function. It does treat
entry points special, but they're not required to be called `main` so
we have a different attribute annotation to mark them.

At the moment this change really just changes the mangling of functions
named `main` in the Itanium mangling.

Fixes llvm#110517
