Jordy Rose 6d5a8caac3 [analyzer] Convert many existing tests to use clang_analyzer_eval.

Jordy Rose 728be7f6ac [analyzer] Rework both constraint managers to handle mixed-type comparisons. 
This involves keeping track of three separate types: the symbol type, the
adjustment type, and the comparison type. For example, in "$x + 5 > 0ULL",
if the type of $x is 'signed char', the adjustment type is 'int' and the
comparison type is 'unsigned long long'. Most of the time these three types
will be the same, but we should still do the right thing when the
comparison value is out of range, and wraparound should be calculated in
the adjustment type.

This also re-disables an out-of-bounds test; we were extracting the symbol
from non-additive SymIntExprs, but then throwing away the integer.

Sorry for the large patch; both the basic and range constraint managers needed
to be updated together, since they share code in SimpleConstraintManager.

Benjamin Kramer 322ab26387 Don't depend on system headers in clang -cc1 tests. 
The constant was copied from clang's limits.h.
