Fix code generation for buildtin_longjmp with CET.
According to the description of inssp instruction from Intel CET it
adusts the shadow stack pointer (ssp) only by value in the range of
[0..255]. As a number of adjustment could be greater than 255 there
should be a loop generated to adjust ssp.
gcc/
* config/i386/i386.md: Add a loop with incssp.
* testsuite/gcc.target/i386/cet-sjlj-1.c: Fix test.
* testsuite/gcc.target/i386/cet-sjlj-4.c: Likewise.
