Move tests that have C/C++ sources into the appropriate directory. This
allows them to be selected for testing based on whether llvm-gcc is
present or not.

According to the spec (C++ 5p6[expr]), we need to adjust "T&" to
"T" before further analysis. We do this via the "implicit cast"
thingy.

there is no compelling need to return the converted type. If both expression type's are arithmetic, then
both types will always be the same. If they aren't (for pointer/int types, say), then the
types will be different. The client is responsible for distinguishing...

to quickly fix a regression. Avoiding them entirely is a much cleaner solution. Clients of
UsualArithmeticConversions should simply call getType() on the expression to get the
converted type. In practice, only a small number of routines care about this.

isPointerType and isVectorType to only look through a single level of typedef
when one is present. For this invalid code:
typedef float float4 __attribute__((vector_size(16)));
typedef int int4 __attribute__((vector_size(16)));
typedef int4* int4p;
void test(float4 a, int4p result, int i) {
result[i] = a;
}
we now get:
t.c:5:15: error: incompatible types assigning 'float4' to 'int4'
result[i] = a;
~~~~~~~~~ ^ ~
instead of:
t.c:5:15: error: incompatible types assigning 'float4' to 'int __attribute__((vector_size(16)))'
result[i] = a;
~~~~~~~~~ ^ ~
The rest of the type predicates should be upgraded to do the same thing.
llvm-svn: 39932
needs to query the expression for the type. Since both these functions guarantee the expression
contains a valid type, removed old/vacuous asserts (from code calling both of these routines).

llvm-gcc build to succeed. Without this change it fails in libstdc++
compilation. This causes no regressions in dejagnu tests. However,
someone who knows this code better might want to review it.

have an error, and refector out the code for binary operators into
ConstantFoldBinaryFP and use it for all binary floating-point operations
which may have an error. These functions still rely exclusively on errno
to detect errors though.

accurate diagnostics. For test/Lexer/comments.c we now emit:
int x = 000000080; /* expected-error {{invalid digit}} */
^
constants.c:7:4: error: invalid digit '8' in octal constant
00080; /* expected-error {{invalid digit}} */
^
The last line is due to an escaped newline. The full line looks like:
int y = 0000\
00080; /* expected-error {{invalid digit}} */
Previously, we emitted:
constants.c:4:9: error: invalid digit '8' in octal constant
int x = 000000080; /* expected-error {{invalid digit}} */
^
constants.c:6:9: error: invalid digit '8' in octal constant
int y = 0000\
^
which isn't too bad, but the new way is better for the user,
regardless of whether there is an escaped newline or not.
All the other lexer-related diagnostics should switch over
to using AdvanceToTokenCharacter where appropriate. Help
wanted :).
This implements test/Lexer/constants.c.

specifying the start of a token and a logical (phase 3) character number,
returns a sloc representing the input character corresponding to it.
