allow the xform if we have a definition, but otherwise we don't
want to risk that we're changing the abi in a subtle way.  On
X86-64, for example, varargs require passing stuff in %al.

Fix tiny error in CFG construction for BinaryConditionalOperators, making sure the branch always has two successors.  Also teach Environment::getSVal() about OpaqueValueExprs.

This fixes a crash reported in PR9287, and also fixes a false positive involving the value of such ternary
expressions not properly getting propagated.

simplify some of the unit mismatch in the parts of the code where sizes are
known to be exact multiples of the width of the char type.

Assertions in the getters help guard against accidentally converting to
CharUnits when sizes are not exact multiples of the char width.

expressions. Consider the code:

  int64_t i = 10 << 30;

This compiles fine, but most developers expect it to produce the value
for 10 gigs, not -2 gigs. This is actually undefined behavior because
the LHS is a signed integer type.

The warning is currently gated behind -Wshift-overflow.

There is a special case where only the sign bit is overridden that gets
a custom error message and is by default ignored. This case is much less
likely to cause observed buggy behavior, it's just undefined behavior
according to the spec. This warning can be enabled with
-Wshift-sign-overflow.

fixes by me.
