The operand flag word for ISD::INLINEASM nodes now contains a 15-bit
memory constraint ID when the operand kind is Kind_Mem. This constraint
ID is a numeric equivalent to the constraint code string and is converted
with a target specific hook in TargetLowering.
This patch maps all memory constraints to InlineAsm::Constraint_m so there
is no functional change at this point. It just proves that using these
previously unused bits in the encoding of the flag word doesn't break
anything.
The next patch will make each target preserve the current mapping of
everything to Constraint_m for itself while changing the target independent
implementation of the hook to return Constraint_Unknown appropriately. Each
target will then be adapted in separate patches to use appropriate
Constraint_* values.
PR22883 was caused the matching operands copying the whole of the operand flags
for the matched operand. This included the constraint id which needed to be
replaced with the operand number. This has been fixed with a conversion
function. Following on from this, matching operands also used the operand
number as the constraint id. This has been fixed by looking up the matched
operand and taking it from there.

The value of some_values (pointer) expeced to start by 0x0 but nothing
requires that the first digit of the address be '0'.
This CL change the expectation to check only for a value starting with 0x.

Summary: Make emitMipsAbiFlags a direct member of MipsTargetELFStreamer, as that's the only place where it's used, and remove the empty implementations from MipsTargetStreamer and MipsTargetAsmStreamer.

* On Android (at least on platfrom-21 x86) the dynamic linker reports the
executable with its full path
* Use the platform path of the executable when storing it into the cache
(used to identify the SO entry for the executable) as this is the path
what will be reported by the dynamic linker. If the platform path isn't
set (local debugging) then it falls back to the normal file path.

The file path is currently required on android because the executables
only contain the name of the system libraries without their path. This
CL add an extra field to the qModuleInfo packet to return the full path
of a modul and add logic to locate a shared module on android.

Summary:
SymbolFileDWARF was not respecting the include_inlines argument in function lookup in all code
paths. This resulted in an attempt to call an inlined function during expression evaluation,
which is impossible, and usually resulted in a segfault in the inferior. This patch makes sure
include_inlines is respected in all code paths.

headers even if they arrived when merging non-system modules.
The idea of this code is that we don't want to warn the user about
macros defined multiple times by their system headers with slightly
different definitions. We should have this behavior if either the
macro comes from a system module, or the definition within the module
comes from a system header. Previously, we would warn on ambiguous
macros being merged when they came from a users modules even though they
only showed up via system headers.
By surviving this we can handle common system header macro differences
like differing 'const' qualification of pointers due to some headers
predating 'const' being valid in C code, even when those systems headers
are pre-built into a system module.

This works by creating a command backed by a class whose interface should - at least - include
def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)
What works:
- adding a command via command script add --class
- calling a thusly created command
What is missing:
- support for custom help
- test cases
The missing parts will follow over the next couple of days
This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)

There's a missed optimization opportunity where we could look at the full chain of computation and take the intersection of the flags instead of only looking one instruction deep.

This is complicated by the fact that we can't simply use side-effecting
calls in an argument list without losing all guarantees about the order
they're emitted. To keep things deterministic we use tuples and brace
initialization, which thankfully guarantees evaluation order.
No functionality change intended.

This should complete the job started in r231794 and continued in r232045:
We want to replace as much custom x86 shuffling via intrinsics
as possible because pushing the code down the generic shuffle
optimization path allows for better codegen and less complexity
in LLVM.
AVX2 introduced proper integer variants of the hacked integer insert/extract
C intrinsics that were created for this same functionality with AVX1.
This should complete the removal of insert/extract128 intrinsics.
The Clang precursor patch for this change was checked in at r232109.
