ARM: Teach assembler to enforce constraint for Thumb2 LDRD (literal/immediate) destination register operands.

LDRD<c> <Rt>, <Rt2>, <label>
LDRD<c> <Rt>, <Rt2>, [<Rn>{, #+/-<imm>}]
LDRD<c> <Rt>, <Rt2>, [<Rn>], #+/-<imm>
LDRD<c> <Rt>, <Rt2>, [<Rn>, #+/-<imm>]!

As specified in A8.8.72/A8.8.73 in the ARM ARM, the T1 encoding has a constraint which enforces that Rt != Rt2.

If this constraint is not met the result of executing the instruction will be unpredictable.

Fixes rdar://14479780.

lowerMSABinaryIntr, lowerMSABinaryImmIntr, lowerMSABranchIntr,
and lowerMSAUnaryIntr were trivially small functions. Inlined them into
their callers.

lowerMSASplat now takes its callers SDLoc instead of making a new one.

No functional change.

Summary:
The width of the first inserted tab character depends on the initial
column, so we need to handle the first tab in a special manner.

We previously handled one-dimensional arrays but didn't consider the
general case.  The fix is simple: keep going through subsequent
dimensions until we get to the base element.

  template <typename T>
  // T should be one of {A, B}.

Put HasAVX512 predicate on some patterns to properly disable them when AVX512 isn't enabled. Currently it works simply because the SSE and AVX version of the same patterns are checked first in the DAG isel table.

The intent of getTypeOperand() was to yield an unqualified type.
However QualType::getUnqualifiedType() does not strip away qualifiers on
arrays.

N.B.  This worked fine when typeid() was applied to an expression
because we would inject as implicit cast to the unqualified array type
in the AST.

Functions declared as constexpr must have their parsing delayed in
-fdelayed-template-parsing mode so as not to upset later template
instantiation.

N.B. My reading of the standard makes it seem like delayed template
parsing is at odds with constexpr.  We may want to make refinements in
other places in clang to make constexpr play nicer with this feature.

This fixes PR17334.

and then share it.

not have breakpoints set on it inserted into code that does have a valid line number.  So allow
that line number, and the ThreadPlanStepRange should just continue stepping over 0 line ranges
as if they had the same line number as whatever we were previously stepping through.

This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.
