Instead of lowering SELECT to SELECT_CC which is further lowered later
immediately call the SELECT_CC lowering code. This is preferable
because:
- Avoids an unnecessary roundtrip through the legalization queues with
an intermediate node.
- More importantly: Lowered operations get visited last leading to SELECT_CC
getting visited with legalized operands and unlegalized ones for preexisting
SELECT_CC nodes. This does not hurt the current code (hence no testcase) but
is required for another patch I am working on.

This reverts commit r234329, which insufficiently appeased older
`clang`s (apparently that wasn't the only call site). r234331 was a
more complete fix.

because the compiler looked at its SourceLocation and
decided it had already handled it.
Also updated the relevant test case.

A bot is failing [1] after r234326, apparently because this code doesn't
do what I think it should:
template <class U>
explicit MDTupleTypedArrayWrapper(
const U &Tuple,
typename std::enable_if<
std::is_constructible<const MDTuple *, U>::value>::type * = nullptr)
: N(Tuple) {}
Just be explicit for now.

Update a few calls to `DIBuilder` now that `MDTuple` array-wrappers
don't have implicit conversions to `MDTuple*`. I may circle back and
update `DIBuilder` to take arrays here, to make it easier for the
callers.

There were four almost identical implementations of calculating/updating
the register pressure for a certain MachineInstr. Cleanup to have a
single implementation (well, controlled with two bool flags until this
is cleaned up more).
No functional changes intended.
Tested by verify that there are no binary changes in the entire llvm
test-suite. A new test was added separately in r234309 as it revealed a
pre-existing error in the register pressure calculation.

Summary:
What looks like a typo has caused the scripts/Python directory to be compiled on non-Windows
platforms even with LLDB_DISABLE_PYTHON, which failed if Python.h was unavaiable. This changes
the condition to avoid compilation if LLDB_DISABLE_PYTHON is set.
Test Plan: Remove Python.h, verify compilation is successful.

This is not possible when using the IAS for MIPS, but it is possible when using the IAS for other architectures and when using GAS for MIPS.

Summary:
The loop which emits AssemblerPredicate conditions also links them together by emitting a '&&'.
If the 1st predicate is not an AssemblerPredicate, while the 2nd one is, nothing gets emitted for the 1st one, but we still emit the '&&' because of the 2nd predicate.
This generated code looks like "( && Cond2)" and is invalid.

ELF symbol tables on aarch64 may contains some mapping symbols. They
provide information about the underlying data but interfere with symbol
look-up of lldb. They are already ignored on arm32. With this CL they
will be ignored on aarch64 also.

Make PLT entry atoms represent mapping symbols in the Release mode,
while in the Debug mode they are still function-like symbols
with regular names.
It's legal that mapping symbols denote unnamed parts of code,
and PLT entries are not required to have function-like names.

ensure that section addresses are distinct.
mapSectionAddress will fail if two sections are allocated the same address,
which can happen if any section has zero size (since malloc(0) is implementation
defined). Unfortunately I've been unable to repro this with a simple test case.

Replace all uses of `DITypedArray<>` with `MDTupleTypedArrayWrapper<>`
and `MDTypeRefArray`. The APIs are completely different, but the
provided functionality is the same: treat an `MDTuple` as if it's an
array of a particular element type.
To simplify this patch a bit, I've temporarily typedef'ed
`DebugNodeArray` to `DIArray` and `MDTypeRefArray` to `DITypeArray`.
I've also temporarily conditionalized the accessors to check for null --
eventually these should be changed to asserts and the callers should
check for null themselves.
There's a tiny accompanying patch to clang.

Remove special iterators from `DIExpression` in favour of same in
`MDExpression`. There should be no functionality change here.
Note that the APIs are slightly different: `getArg(unsigned)` counts
from 0, not 1, in the `MDExpression` version of the iterator.

Maybe we can interpret alignment 0 as "don't care", but for
consistency, it's good to set 1 instead of 0 where we allow
any alignments.
