Ted Kremenek f2ca8ec2b9 Hoist retrieval of Expr* into caller. No functionality change. 
Just makes the code a little cleaner, and easier to reason about.

Argyrios Kyrtzidis 8c8684bbe1 [preprocessor] Don't warn about "disabled expansion of recursive macro" 
for "#define X X".

This is a pattern that, for example, stdbool.h uses.

Jordan Rose 4cf4f8a5d4 [analyzer] Model trivial copy/move ctors with an aggregate bind. 
This is faster for the analyzer to process than inlining the constructor
and performing a member-wise copy, and it also solves the problem of
warning when a partially-initialized POD struct is copied.

Before:
  CGPoint p;
  p.x = 0;
  CGPoint p2 = p; <-- assigned value is garbage or undefined

After:
  CGPoint p;
  p.x = 0;
  CGPoint p2 = p; // no-warning

This matches our behavior in C, where we don't see a field-by-field copy.

Manman Ren 81dcc62805 Linker: correctly link in dbg.declare 
Given source IR:
call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !14), !dbg !15
we used to generate 
call void @llvm.dbg.declare(metadata !27, metadata !28), !dbg !29
!27 = metadata !{null}

With this patch, we will correctly generate
call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !27), !dbg !28

Looking up %argc.addr in ValueMap will return null, since %argc.addr is already
correctly set up, we can use identity mapping.

Dmitri Gribenko 28800da1b3 Comment parsing: resolve more named character references 
This reimplements r173850 with a better approach:
(1) use a TableGen-generated matcher instead of doing a linear search;
(2) avoid allocations for new strings by converting code points to string
    iterals with TableGen.

Tim Northover da16507111 Also promote fp16 types to double when they're anonymous variadic arguments. 
__fp16 isn't covered by the standard, but this resolves the oddity that float
gets promoted when passed variadically, but not the smaller type. This is
required by the AArch64 ABI, and a sane action elsewhere.
