Siegfried Pammer	17e6649ba8	Fix #3954 : name the entry point of a top-level program 'Main' Roslyn compiles top-level statements into a synthesized Program class whose entry point is called '<Main>$', a name that cannot be declared in C#. Decompiled output kept it verbatim (escaped to _003CMain_003E_0024 when exporting a project), and since C# accepts only a method called 'Main' as an entry point, the exported executable did not compile (CS5001). Give that method the name 'Main'. Per the decision recorded in #829 we do not reconstruct top-level statements, so this is the level of support the output needs to compile. An async top-level program needs the name in a different place: it compiles to '<Main>$' holding the statements plus a '<Main>' entry point that only awaits it. That wrapper carries the .entrypoint marker but is hidden from the output, so the name goes to the method it awaits instead - unless AsyncAwait is off, when the wrapper is emitted and keeps the name itself.

Fix #3954 : name the entry point of a top-level program 'Main'

Roslyn compiles top-level statements into a synthesized Program class
whose entry point is called '<Main>$', a name that cannot be declared
in C#. Decompiled output kept it verbatim (escaped to
_003CMain_003E_0024 when exporting a project), and since C# accepts
only a method called 'Main' as an entry point, the exported executable
did not compile (CS5001).

Give that method the name 'Main'. Per the decision recorded in #829 we
do not reconstruct top-level statements, so this is the level of
support the output needs to compile.

An async top-level program needs the name in a different place: it
compiles to '<Main>$' holding the statements plus a '<Main>' entry
point that only awaits it. That wrapper carries the .entrypoint marker
but is hidden from the output, so the name goes to the method it
awaits instead - unless AsyncAwait is off, when the wrapper is
emitted and keeps the name itself.
