* [Bug tree-optimization/21289] New: A numeric range is spoiled by a symblic one in VRP

Consider
int
foo (int a, int b)
{
if (a == 1)
if (a < b)
if (a == 1)
return 1;
return 0;
}
VRP does not remove the third "if" even though 'a' is known to be 1.
This is because the symbolic range obtained from the second "if"
spoils the numeric range [1, 1] obtained from the first "if".
extract_range_from_assert tries to refine a range from an ASSERT_EXPR
if there is another range previously available, but in this case,
VRP cannot prove that [1,1] and [-INF, b-1] intersects,
it does not refine a range.

Confirmed, to me if the range of a variable is not really a range but one value, it should always merge. I
think that is safe.

It's only safe if both old ranges dominate the new range, as it does here.

Another case of a numeric value range spoiled by a symbolic one:
int
foo (int a, int b)
{
if (a == 0)
return 0;
if (a == b)
if (a == 0)
return 123;
return 456;
}
Reduced from c-common.c.
