gcc: update contents and descriptions

Add lto-dump and libitm, and reword description for liblto_plugin
because it's actually used by libbfd (from binutils).

107 <para>In this section, the test suite for GCC is considered
108 important, but it takes a long time. First time builders are
109 encouraged to not skip it. The time to run the tests can be
110 reduced significantly by adding -jx to the make command below

143 <para>In libstdc++, one test named <filename>49745.cc</filename> is

145 changed.</para>
146
147 <para>In libstdc++, one numpunct test and six tests related to get_time are
148 known to fail. These are all because the locale definitions in glibc have
149 changed but libstdc++ does not currently support those changes.</para>
150
151 <para>A few unexpected failures cannot always be avoided. The GCC developers
152 are usually aware of these issues, but have not resolved them yet.
153 Unless the test results are vastly different from those at the above URL,
154 it is safe to continue.</para>

156 <!--note><para>
157 On some combinations of kernel configuration and AMD processors
158 there may be more than 1100 failures in the gcc.target/i386/mpx
159 tests (which are designed to test the MPX option on recent
160 Intel processors). These can safely be ignored on AMD
161 processors. These tests will also fail on Intel processors if MPX support
162 is not enabled in the kernel even though it is present on the CPU.
