Bob Wilson f96715d7f0 Remove broken command to copy tblgen tool. 
tblgen has been renamed to llvm-tblgen so this command has been failing,
and it's no longer needed because llvm-tblgen is already installed by default.

Benjamin Kramer d90b595599 Reenable building with -fvisibility-inlines-hidden. 
This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.

We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).

IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

Douglas Gregor 464b0ca61a Serialize the AST reader's mapping from canonical declarations to the 
set of (previously-canonical) declaration IDs to the module file, so
that future AST reader instances that load the module know which
declarations are merged. This is important in the fairly tricky case
where a declaration of an entity, e.g.,

  @class X;

occurs before the import of a module that also declares that
entity. We merge the declarations, and record the fact that the
declaration of X loaded from the module was merged into the (now
canonical) declaration of X that we parsed.

Chad Rosier 388769427d Reinstate r146578; it doesn't appear to be the cause of some recent execution- 
time regressions.  In general, it is beneficial to compile-time.

Fix for bug #11429: Wrong behaviour for switches. Small improvement for code
size heuristics.

Jim Grosbach f0d25117c6 ARM VFP add encoding of the bitcount to fixed-point<-->floating point. insns. 
The value from the operands isn't right yet, but we weren't encoding it at
all previously. The parser needs to twiddle the values when building the
instruction.

Jim Ingham ef65160016 Improve the x86_64 return value decoder to handle most structure returns. 
Switch from GetReturnValue, which was hardly ever used, to GetReturnValueObject
which is much more convenient.

Chandler Carruth b024aa021d Make the unreachable probability much much heavier. The previous 
probability wouldn't be considered "hot" in some weird loop structures
or other compounding probability patterns. This makes it much harder to
confuse, but isn't really a principled fix. I'd actually like it if we
could model a zero probability, as it would make this much easier to
reason about. Suggestions for how to do this better are welcome.
