Borislav Petkov a268fcfaa6 x86, asm: Thin down SAVE/RESTORE_* asm macros
Use dwarf2 cfi annotation macros, making SAVE/RESTORE_* marginally more
readable.

No functionality change.

Jan Beulich 3234282f33 x86, asm: Fix CFI macro invocations to deal with shortcomings in gas
gas prior to (perhaps) 2.16.90 has problems with passing non-
parenthesized expressions containing spaces to macros. Spaces, however,
get inserted by cpp between any macro expanding to a number and a
subsequent + or -. For the +, current x86 gas then removes the space
again (future gas may not do so), but for the - the space gets retained
and is then considered a separator between macro arguments.

Fix the respective definitions for both the - and + cases, so that they
neither contain spaces nor make cpp insert any (the latter by adding
seemingly redundant parentheses).
