Peter Maydell 850d5e330a linux-user: Suppress address-of-packed-member warnings in __get/put_user_e 
Our __get_user_e() and __put_user_e() macros cause newer versions
of clang to generate false-positive -Waddress-of-packed-member
warnings if they are passed the address of a member of a packed
struct (see https://bugs.llvm.org/show_bug.cgi?id=39113).
Suppress these using the _Pragma() operator. Unfortunately
_Pragma() support in gcc is broken in some gcc versions and
in some usage contexts, so we limit the pragma usage here to clang.

To put in the pragmas we need to convert the macros from
expressions to statements, but all the callsites effectively
treat them as statements already so this is OK.
