commit r15-3258-g3c9338b532fd609f5cc1c50d6a4e77e0e1ab3bc5

Tweak documentation of ASM_INPUT_P
The documentation of ASM_INPUT_P implied that the flag has no
effect on ASM_EXPRs that have operands (and which therefore must be
extended asms). In fact we require ASM_INPUT_P to be false for all
extended asms.
gcc/
* tree.h (ASM_INPUT_P): Fix documentation.
