WebCore fails to build with trunk clang: error: 'register' storage class specifier is deprecated [-Werror,-Wdeprecated-register]
<http://webkit.org/b/119932>
<rdar://problem/14764085>

Reviewed by Darin Adler.

Add pragma statements to ignore -Wdeprecated-register warnings
in generated code.  Also ignore -Wunknown-pragmas so this
doesn't cause a build failure in older versions of clang.

* css/makeprop.pl:
(WebCore::findProperty): Remove register hints from parameters.
* css/makevalues.pl:
(WebCore::findValue): Ditto.
* platform/ColorData.gperf:
(WebCore::findColor): Ditto.
