This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the sixth batch of tests being updated (there are a significant
number of other tests left to be updated).
This changes the methods in CGExprScalar to use
FixedPointBuilder to generate IR for fixed-point
conversions and operations.
Since FixedPointBuilder emits padded operations slightly
differently than the original code, some tests change.

The tests were not written with update_cc_test_checks
in mind, which make them difficult to update. Fix this.
Also, some of the consteval tests were outright broken,
since the CHECK lines were wrong.
Other than this, the semantics of the tests are preserved.
Summary:
Using the result semantic is wrong in some cases, such as
unsigned fixed-point + signed integer. In this case, the
result semantic is unsigned and the common semantic is
signed.

This patch includes logic for constant expression evaluation of fixed point additions.

This patch covers addition between fixed point types and other fixed point
types or integers, using the conversion rules described in 4.1.4 of N1169.
Usual arithmetic rules do not apply to binary operations when one of the
operands is a fixed point type, and the result of the operation must be
calculated with the full precision of the operands, so we should not perform
any casting to a common type.
This patch does not include constant expression evaluation for addition of
fixed point types. That will be addressed in another patch since I think this
one is already big enough.
