    Fix build with clang 10
    
    This contains a grab bag of fixes to fix the build with clang 10.
    
    - https://github.com/dotnet/coreclr/pull/23075
    
      Fix missing includes in coreclr/src/debug/createdump/
    
    - https://github.com/dotnet/runtime/pull/33096
    
      SList::Init: add missing constructor
    
    - A subset of https://github.com/dotnet/coreclr/pull/22129
    
      Just the parts that introduce the THROW_DECL macro in pal.h
    
    - https://github.com/dotnet/runtime/pull/32837
    
      This fixes THROW_DECL introduce in the previous PR to work with clang, which
      is required in clang 10.
    
    - One new change:
    
      In a significant divergance, this commits adds more THROW_DECL macros
      to all the math functions to address a ton of errors pointed out when
      building SOS:

        /usr/include/bits/mathcalls.h:53:13: error: exception specification in declaration does not match previous declaration
        __MATHCALL (acos,, (_Mdouble_ __x));
                    ^
        /home/omajid/devel/dotnet/coreclr/src/pal/inc/pal.h:4395:26: note: previous declaration is here
        PALIMPORT double __cdecl acos(double);
                                 ^
    
      Then, to make sure the declarations and implementations match, it adds
      THROW_DECL to the definitions in src/pal/src/cruntime/math.cpp
