Implement SD-6: SG10 Feature Test Recommendations
2014-10-01 Edward Smith-Rowland <3dw4rd@verizon.net>
Implement SD-6: SG10 Feature Test Recommendations
* internal.h (lexer_state, spec_nodes): Add in__has_include__.
* directives.c: Support __has_include__ builtin.
* expr.c (parse_has_include): New function to parse __has_include__
builtin; (eval_token()): Use it.
* files.c (_cpp_has_header()): New funtion to look for header;
(open_file_failed()): Not an error to not find a header file for
__has_include__.
* identifiers.c (_cpp_init_hashtable()): Add entry for __has_include__.
* pch.c (cpp_read_state): Lookup __has_include__.
* traditional.c (enum ls, _cpp_scan_out_logical_line()): Walk through
__has_include__ statements.

Implement SD-6: SG10 Feature Test Recommendations
* c-cppbuiltin.c (c_cpp_builtins()): Define language feature
macros and the __has_header macro.
