ea1dbad689 Rename profile_rt.so to libprofile_rt.so under configure+make (it already was 
under cmake).

Add libprofile_rt.a so that we can tell clang to link against it in --coverage
mode. Also turn it on by default in cmake builds.

Oscar, this touches a change you made for EXCLUDE_FROM_ALL support -- I think
I've done the right thing, but please let me know (or fix and commit) if not!

4e13009d4f We require threse bits to be zero, too. 
This shouldn't happen in practice because the icmp would be a constant.

40c59f95d7 Only read *predecessor once so as to fix a theoretical issue where it changes 
between two reads (threading).

Fix an off-by-one in the indirect counter table that I meant to revert after an
earlier experiment. Whoops!

Implement GCOV_PREFIX. Doesn't handle GCOV_PREFIX_STRIP yet.

Fix an off-by-one in string emission. Extra whoops!

Tolerate DISubprograms that have null Function*'s attached to them. I don't yet
understand what this means, but it happens when you have a global static with
a non-trivial constructor/destructor.

Fix a crash on switch statements with a single successor (default-only).

a4696ee0ac final step needed to resolve PR6627, which allows us to flatten the code down to 
a nice and tidy:
  %x1 = load i32* %0, align 4
  %1 = icmp eq i32 %x1, 1179403647
  br i1 %1, label %if.then, label %if.end

instead of doing lots of loads and branches.  May the FreeBSD bootloader
long fit in its allocated space.

5ea854079d Fix a bug in tblgen that caused incorrect encodings on instructions that specified operands with "bit" instead of "bits<1>". 
Unfortunately, my only testcase for this is fragile, and the ARM AsmParser can't round trip the instruction in question.
