[committed] Fix PR 62301

[Richard Sandiford]

This patch fixes a stupid typo in:

2014-08-28  Richard Sandiford  <rdsandif...@googlemail.com>

    * rtl.h (get_pool_constant, rtx_referenced_p): Replace rtx parameters
    with const_rtx parameters.
    * varasm.c (get_pool_constant): Likewise.
    * rtlanal.c (rtx_referenced_p_1): Delete.
    (rtx_referenced_p): Use FOR_EACH_SUBRTX instead of for_each_rtx.
    Assert that the rtx we're looking for is nonnull.  Allow searches
    for constant pool SYMBOL_REFs.

which caused a boostrap failure on PowerPC.  Bootstrapped on
powerpc64-linux-gnu and installed as obvious.

Thanks,
Richard
