REGRESSION(r226269): 60 JSC test failures on ARMv7
https://bugs.webkit.org/show_bug.cgi?id=181163

Patch by Zan Dobersek <zdobersek@igalia.com> on 2017-12-26
Reviewed by Yusuke Suzuki.

In r226269, DFG::SpeculativeJIT::compile() changed behavior for the
GetDirectPname operation on non-x86 platforms, switching to using
GPRFlushedCallResult registers for the payload and tag pair of the
return value (through the JSValueRegsFlushedCallResult struct). This
tripped about 60 test cases on ARMv7.

As before this change, GPRTemporary registers should be used, but this
can now be done through a JSValueRegsTemporary object.
