CostModel: increase the default cost of supported floating point operations from 1 to two. Fixed a few tests that changes because now the cost of one insert + a vector operation on two doubles is lower than two scalar operations on doubles.

<rdar://problem/13643854> Only emit ambiguous-expansion warnings when at least one of the macro definitions comes from a non-system header.

This slightly weakens the heuristic introduced in r178109.

when parsing MS-style inline assembly.  No functional change intended.

llvm-svn: 179407

We had been defining Neon intrinsics as "static" with always_inline attributes.
If you use them from an extern inline function, you get a warning, e.g.:

static function 'vadd_u8' is used in an inline function with external linkage

This change simply adds the inline keyword to avoid that warning.

Made some fixes to the OperatingSystemPython class:
- If any thread dictionary contains any "core=N" key/value pairs then the threads obtained from the lldb_private::Process itself will be placed inside the ThreadMemory threads and will be used to get the information for a thread. 
- Cleaned up all the places where a thread inside a thread was causing problems

According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes.
The MC disassembler was not obeying this when the offset is 0.
It was producing instructions like: str r0, [r1]!.
Correct syntax is: str r0, [r1, #0]!.

This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used.

There are few cases where we can track the region, but cannot print the note,
which makes the testing limited. (Though, I’ve tested this manually by making
all regions non-printable.) Even though the applicability is limited now, the enhancement
will be more relevant as we start tracking more regions.

TableGen will not combine nested list 'let' bindings into a single list, and
instead uses only the inner scope. As a result, several instruction definitions
were missing implicit register defs that were in outer scopes. This de-nests
these scopes and makes all instructions have only one let binding which sets
implicit register definitions.

Don't classify idiv/udiv as a reduction operation. Integer division is lossy.
For example : (1 / 2) * 4 != 4/2.

Example:

int a[] = { 2, 5, 2, 2}
int x = 80;

for()
  x /= a[i];

Scalar:
  x /= 2 // = 40
  x /= 5 // = 8
  x /= 2 // = 4
  x /= 2 // = 2

Vectorized:

 <80, 1> / <2,5> //= <40,0>
 <40, 0> / <2,2> //= <20,0>

 20*0 = 0

Previously we'd only detect structural errors on the very first level.
This leads to incorrectly balanced braces not being discovered, and thus
incorrect indentation.

This change fixes the problem by:
- changing the parser to use an error state that can be detected
  anywhere inside the productions, for example if we get an eof on
  SOME_MACRO({ some block <eof>
- previously we'd never break lines when we discovered a structural
  error; now we break even in the case of a structural error if there
  are two unwrapped lines within the same line; thus,
  void f() { while (true) { g(); y(); } }
  will still be re-formatted, even if there's missing braces somewhere
  in the file
- still exclude macro definitions from generating structural error;
  macro definitions are inbalanced snippets

It turns out some platforms (e.g. Windows) lay out their llvm-mc slightly
differently with extra newlines; there was no real reason for the test lines to
be consecutive, so this relaxes the FileCheck.
