[PATCH] Combine location with block using block_locations

[Dehao Chen]

Hi,

As expected, since this patch was checked in yesterday, there are 4
bugs exposed (1 fixed, 1 patch ready, 2 TBD):

1. http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01413.html
Failed targets such as arm and mips. Fixed by r191510

2. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54649
Failed Go bootstrap (I didn't test --enable-language=go). The problem
is when we set the line number for stmts in the finally block
(tree-eh.c), we don't want to change its block info.
A fix was proposed: http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01513.html

3. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54645
All PCH related tests fail intermittently. (They didn't manifest when
I was doing the test...)
The cause of the problem is: when reading PCH data, the line_table is
also read from PCH files. But the location_adhoc_data_map is not
managed by GC, thus is not read in from PCH file (only a pointer is
read in).
I'll try to provide a patch to resolve the problem by the end of Friday.

4. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54650
Failed one regression test in libgomp (I didn't know that there are
regression tests for libraries before...)
This error should be a bug exposed by this patch. I'll try to provide
a patch as soon as possible.

Thanks,
Dehao
