[patch] Change the default of TARGET_STRUCT_VALUE_RTX.

- Subject: [patch] Change the default of TARGET_STRUCT_VALUE_RTX.
Hi,
Attached is a patch to change the default of TARGET_STRUCT_VALUE_RTX.
Currently, the default of TARGET_STRUCT_VALUE_RTX is to call abort(),
which is not very useful, and indeed no port uses the default.
The patch creates a resonable default value for
TARGET_STRUCT_VALUE_RTX, which is to put the pointer to a structure as
the first invisible argument.
Bootstrapped on i686-pc-linux-gnu. OK to apply?
