f0e92a8bca llvm-profdata: Don't pipe stderr into show for the tests
Some text shows up on stderr when using guard malloc, and this test
was trying to treat that as input to llvm-profdata show. There's no
reason to pipe stderr into show at all here.

7afe0000f6 ARM IAS: properly handle function entries in .thumb
When a label is parsed, check if there is type information available for the
label.  If so, check if the symbol is a function.  If the symbol is a function
and we are in thumb mode and no explicit thumb_func has been emitted, adjust the
symbol data to indicate that the function definition is a thumb function.

The application of this inferencing is improved value handling in the object
file (the required thumb bit is set on symbols which are thumb functions).  It
also helps improve compatibility with binutils.

The one complication that arises from this handling is the MCAsmStreamer.  The
default implementation of getOrCreateSymbolData in MCStreamer does not support
tracking the symbol data.  In order to support the semantics of thumb functions,
track symbol data in assembly streamer.  Although O(n) in number of labels in
the TU, this is already done in various other streamers and as such the memory
overhead is not a practical concern in this scenario.

62f4b48fc1 [Constant Hoisting] Erase dead cast instructions.
The cleanup code that removes dead cast instructions only removed them from the

5cfc91c9a5 [Constant Hoisting] Fix multiple entries for the same basic block in PHI nodes.
A PHI node usually has only one value/basic block pair per incoming basic block.
In the case of a switch statement it is possible that a following PHI node may
have more than one such pair per incoming basic block. E.g.:
%0 = phi i64 [ 123456, %case2 ], [ 654321, %Entry ], [ 654321, %Entry ]
This is valid and the verfier doesn't complain, because both values are the
same.

Constant hoisting materializes the constant for each operand separately and the
value is still the same, but the variable names have changed. As a result the
verfier can't recognize anymore that they are the same value and complains.

This fix adds special update code for PHI node in constant hoisting to prevent
this corner case.

This fixes <rdar://problem/16394449>

d47cb57ab8 [DAG] Fix an assertion failure caused by an invalid cast in method 'BuildVectorSDNode::isConstantSplat'
This patch renames method 'isConstantSplat' as 'getConstantSplatValue'
(mainly for consistency reasons), and rewrites its logic to ensure
that we always perform a legal 'cast<ConstantSDNode>'.

Added test shift-combine-crash.ll to verify that DAGCombiner no longer crashes with an assertion failure in the attempt to simplify a vector shift by a vector of all undef counts.

8dbd561a88 Register allocator: add condition to hoist a spill to outer loop.
We make sure a spill is not hoisted to a hotter outer loop by adding
a condition. Hoist a spill to outer loop if there are multiple dependents
(it can be beneficial if more than one dependents are hoisted) or
if DepSV (the hoisting source) is hotter than SV (the hoisting destination).

4d221b3e89 DebugInfo: Omit DW_AT_addr_base from skeletal type units.
Type units have no addresses, so there's no need for DW_AT_addr_base.
This removes another relocation from every skeletal type unit and brings
LLVM's skeletal type units in line with GCC's (containing only
GNU_dwo_name (strp), comp_dir (strp), and GNU_pubnames (flag_present)).

Cary's got some ideas about using str_index in the .o file to reduce
those last two relocations (well, replace two relocations with one
relocation (pointing to the string index) and two indicies)

e85dd7c26d [mips] Correct lowering of VECTOR_SHUFFLE to VSHF.
Summary:
VECTOR_SHUFFLE concatenates the vectors in an vectorwise fashion.
  <0b00, 0b01> + <0b10, 0b11> -> <0b00, 0b01, 0b10, 0b11>
VSHF concatenates the vectors in a bitwise fashion:
  <0b00, 0b01> + <0b10, 0b11> ->
  0b0100       + 0b1110       -> 0b01001110
                                 <0b10, 0b11, 0b00, 0b01>
We must therefore swap the operands to get the correct result.

The test case that discovered the issue was MultiSource/Benchmarks/nbench.

af4c7da306 R600/SI: Use SGPR_(32|64) reg clases when lowering SI_ADDR64_RSRC
The SReg_(32|64) register classes contain special registers in addition
to the numbered SGPRs.  This can lead to machine verifier errors when
these register classes are used as sub-registers for SReg_128, since
SReg_128 only uses the numbered SGPRs.

Replacing SReg_(32|64) with SGPR_(32|64) fixes this problem, since
the SGPR_(32|64) register classes contain only numbered SGPRs.

Tests cases for this are comming in a later commit.
