ada-lex: Ignore warnings about register keyword
Some older versions of flex (such as the one shipped with macOS) generate
code that use the register keyword, which clang warns about. This patch
makes the compiler ignore those warnings for the portion of the code
generated by flex.
gdb/ChangeLog:
* common/diagnostics.h (DIAGNOSTIC_IGNORE_DEPRECATED_REGISTER):
New macro.
* ada-lex.l: Ignore deprecated register warnings.
