Tim Northover 2c45a383a8 ARM: fix more cases where predication may or may not be allowed 
Unfortunately this addresses two issues (by the time I'd disentangled the logic
it wasn't worth putting it back to half-broken):

+ Coprocessor instructions should all be predicable in Thumb mode.
+ BKPT should never be predicable.

Tim Northover 52f77f5cda ARM: allow predicated barriers in Thumb mode 
The barrier instructions are only "always-execute" in ARM mode, they can quite
happily sit inside an IT block in Thumb.

Ulrich Weigand 5a02a02b41 [PowerPC] Accept 17-bit signed immediates for addis 
The assembler currently strictly verifies that immediates for
s16imm operands are in range (-32768 ... 32767).  This matches
the behaviour of the GNU assembler, with one exception: gas
allows, as a special case, operands in an extended range
(-65536 .. 65535) for the addis instruction only (and its
extended mnemonic lis).

The main reason for this seems to be to allow using unsigned
16-bit operands for lis, e.g. like lis %r1, 0xfedc.

Since this has been supported by gas for a long time, and
assembler source code seen "in the wild" actually exploits
this feature, this patch adds equivalent support to LLVM
for compatibility reasons.

Ulrich Weigand fd3ad693e8 [PowerPC] Support symbolic u16imm operands 
Currently, all instructions taking s16imm operands support symbolic
operands.  However, for u16imm operands, we only support actual
immediate integers.  This causes the assembler to reject code like

  ori %r5, %r5, symbol@l

This patch changes the u16imm operand definition to likewise
accept symbolic operands.  In fact, s16imm and u16imm can
share the same encoding routine, now renamed to getImm16Encoding.

Chandler Carruth fc9d259c98 Revert the Darwin half of r184805: "Remove the sysroot (or isysroot) 
restriction from the GCDAProfile.c"

Bill added a much more effective way of coping with the use of errno and
other system interactions for Darwin for now by disabling it on that
platform. Building against the SDK stuff is more fundamental to the
darwin build process.

Andy Gibbs 3ef5ed1ec0 Provide bootstrap support to build only llvm+clang when using cmake. 
Where a source tree is complete with lld, lldb and polly, it may not be possible to use cmake to configure build scripts if the host compiler it not capable of compiling these sub-projects.  This change makes it possible to first build a bootstrap clang compiler when can then be used to build a complete llvm toolchain.  An example bootstrap build sequence could be as follows:

$ mkdir bootstrap
$ cd bootstrap
$ cmake -G 'Unix Makefiles'
        -DCMAKE_BUILD_TYPE:STRING=Release
        -DCMAKE_PREFIX_PATH:STRING=$(pwd)
        -DLLVM_TARGETS_TO_BUILD:STRING=host
        -DLLVM_INCLUDE_TOOLS:STRING=bootstrap-only
        ../source
$ make clang  # build clang only for host

$ cd ..
$ export CC=$(realpath bootstrap/bin)/clang
$ export CXX=$(realpath bootstrap/bin)/clang++

$ mkdir final
$ cd final
$ cmake -G 'Unix Makefiles' ../source
$ make all check-all
