profiledbootstrap on x86_64-linux fails while building go.
Attached is a distilled testcase:
./cc1plus -quiet -O2 -Wall -fprofile-use go.ii -w
go.ii: In function ‘std::basic_string<_CharT, <template-parameter-1-2>,
<template-parameter-1-3> >::~basic_string() [with _CharT =
std::allocator<char>, <template-parameter-1-2> =
std::char_traits<std::allocator<char> >, _Alloc =
std::allocator<std::allocator<char> >]’:
go.ii:116:1: note: file /usr/src/gcc/obj534a/gcc/go.gcda not found, execution
counts estimated
go.ii: In member function ‘Type* Parse::type()’:
go.ii:107:8: internal compiler error: vector VEC(use_pred_info_t,base) index
domain error, in pred_chain_length_cmp at tree-ssa-uninit.c:1626
Please submit a full bug report,
with preprocessed source if appropriate.

go.gcda isn't needed...
