ash: less hackish implementation of evaltreenr()
Defining a function alias with __attribute__ ((alias("evaltree"),__noreturn__))
is not that usual, and clang had a bug which made it misunderstand
this construct.
Switch to:
ALWAYS_INLINE NORETURN evaltreenr() { evaltree(); unreachable(); }
Older gcc's do not know unreachable(), on them we pay the price of having
a few extra calls to abort():
function old new delta
evalsubshell 151 156 +5
evalpipe 357 362 +5
argstr 1141 1144 +3
On newer gcc, code size does not change.
