[COMMITTED] amdgcn: Fix expansion of GCN_BUILTIN_LDEXPV builtin

[Kwok Cheung Yeung]

Hello

This patch fixes a bug in the expansion of GCN_BUILTIN_LDEXPV. As this 
is a double-precision operation, the first argument should be expanded 
as a V64DF expression (instead of V64SF).

Committed to trunk as obvious.
