Andrew Trick 1abe296cfd indvars: Added DisableIVRewrite and WidenIVs.
This adds functionality to remove size/zero extension during indvars
without generating a canonical IV and rewriting all IV users. It's
disabled by default so should have no effect on codegen. Work in progress.

John McCall 3ab847648f Type prefixes of unresolved-names should only be mangled as unresolved-types
if they match that production, i.e. if they're template type parameters
or decltypes (or, as an obvious case not yet described in the ABI document,
if they're template template parameters applied to template arguments).

Jakob Stoklund Olesen 5b5abb4ea1 Don't run this test through -regalloc=basic.
The basic allocator is really bad about hinting, so it doesn't eliminate all
copies when physreg joining is disabled.

Douglas Gregor ed8a29b855 When tag lookup finds something ambiguous, and we're defining a new
tag, filter out those ambiguous names that we found if they aren't
within the declaration context where this newly-defined tag will be
visible.

This is basically a hack, because we really need to fix the lookup of
tag declarations in this case to not find things it
shouldn't. However, it's better than what we had before, and it fixes
<rdar://problem/9168556>.

Alexis Hunt 9d47faf686 Ensure that destructors are properly inovked when an exception leaves
the body of a delegating constructor call.

This means that the delegating constructor implementation should be
complete and correct, though there are some rough edges (diagnostic
quality with the cycle detection and using a deleted destructor).

Jakob Stoklund Olesen f8be385c9b Mark ultra-super-registers QQQQ as call-clobbered instead of the D sub-registers.
LiveVariables doesn't understand that clobbering D0 and D1 completely overwrites
Q0, so if Q0 is live-in to a function, its live range will extend beyond a
function call that only clobbers D0 and D1. This shows up in the
ARM/2009-11-01-NeonMoves test case.

LiveVariables should probably implement the much stricter rules for physreg
liveness that RAFast imposes - a physreg is killed by the first use of any
alias.

Only create a canonical IV for backedge taken count if it will
actually be used by LinearFunctionTestReplace. And some related

Greg Clayton effe5c956b Added new OptionGroup classes for UInt64, UUID, File and Boolean values.
Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules". 

Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]

So you can load individual sections without running a target:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000

Or you can rigidly slide an entire shared library:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000

This should improve bare board debugging when symbol files need to be slid around manually.

Caroline Tice e67afe15b4 Pre-load the Python script interpreter with the following
convenience variables (from the ExecutionContext) each time
it is entered: lldb.debugger, lldb.target, lldb.process, 
lldb.thread, lldb.frame.

If a frame (or thread, process, etc) does not currently exist,
the variable contains the Python value 'None'.

Jakob Stoklund Olesen eaa6ed1ad8 Gracefully handle invalid live ranges. Fix PR9831.
Register coalescing can sometimes create live ranges that end in the middle of a
basic block without any killing instruction. When SplitKit detects this, it will
repair the live range by shrinking it to its uses.

Live range splitting also needs to know about this. When the range shrinks so
much that it becomes allocatable, live range splitting fails because it can't
find a good split point. It is paranoid about making progress, so an allocatable
range is considered an error.

The coalescer should really not be creating these bad live ranges. They appear
when coalescing dead copies.

Duncan Sands 0a9c1246d7 Implement some basic simplifications involving min/max, for example
max(a,b) >= a -> true.  According to my super-optimizer, these are
by far the most common simplifications (of the -instsimplify kind)
that occur in the testsuite and aren't caught by -std-compile-opts.
