John McCall 18a2c2c0b9 Split out -Wconversion warnings about constant precision into their
own subcategory, -Wconstant-conversion, which is on by default.

Tweak the constant folder to give better results in the invalid
case of a negative shift amount.

Implements rdar://problem/6792488

John McCall 62abc944d6 At sabre's request, drop the FP bounds diagnostics down to warnings and file
them under -Wbad-literal.  They're still on by default.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Chris Lattner 8577f62622 Implement -Wfour-char-constants, which is an extension, not an extwarn,
and apparently not part of -Wall

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Chris Lattner 5e4c75f4ef rename -parse-ast-print to -ast-print
rename -parse-ast-dump to -ast-dump
remove -parse-ast, which is redundant with -fsyntax-only

Ted Kremenek 0883fd5817 Removed option "-parse-ast-check" from clang driver. This is now implemented
using "-parse-ast -verify".

Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.

Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.

Chris Lattner bb1b44f004 Make octal constant lexing use AdvanceToTokenCharacter to give more
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.
