GAS has no such directives (not even mingw-w64 GAS has them), so I took
creative license with their names in assembly. I prefixed them all with
"w64_" to avoid namespace collisions, for example. If I discover that GAS
has taken a different approach, I'll change ours to match.

The 'last use' may not be in the same basic block, and we still want a correct
live range.

llvm-svn: 131523

the purposes of the Win64 EH tables, I realized we had no way to tell where
the function ends. (MASM bounds functions with PROC and ENDP keywords.)
Add a directive to delimit the end of the function, and rename the 'frame'
directive to more accurately reflect its duality with the new directive.

LiveInterval::shrinkToUses recomputes the live range from scratch instead of
removing snippets. This should avoid the problem with dangling live ranges.

Leave physreg identity copies alone. They can be created when joining a virtreg
with a physreg. They don't affect register allocation, and they will be removed
by the rewriter.

member functions by making sure that they're on the record before
checking for deletion.

Also make sure source locations are valid to avoid crashes.

Unfortunately, the declare-all-implicit-members approach is still
required in order to ensure that dependency loops do not result in
incorrectly deleting functions (since they are to be deleted at the
declaration point per the standard).

bool
Address::SetLoadAddress (lldb::addr_t load_addr, Target *target);

Added an == and != operator to RegisterValue.

Modified the ThreadPlanTracer to use RegisterValue objects to store the
register values when single stepping. Also modified the output to be a bit
less wide.

Fixed the ABIMacOSX_arm to not overwrite stuff on the stack. Also made the
trivial function call be able to set the ARM/Thumbness of the target 
correctly, and also sets the return value ARM/Thumbness.

Fixed the encoding on the arm s0-s31 and d16 - d31 registers when the default
register set from a standard GDB server register sets.

Start trying to make InstCombine preserve more debug info.  The idea here is to set the debug location on the IRBuilder, which will be then right location in most cases.  This should magically give many transformations debug locations, and fixing places which are missing a debug location will usually just means changing the code creating it to use the IRBuilder.

As an example, the change to InstCombineCalls catches a common case where a call to a bitcast of a function is rewritten.

Chris, does this approach look reasonable?

I hear at least one person crying out in anguish, but it's unfortunately
necessary to avoid infinite loops with mutually dependent constructors
trying to call each other and determine if they are deleted.

It might be possible to go back to the old behavior if we can implement
part-of-file lookups efficiently, or if a solution is discovered by
which we can safely detect and avoid infinite recusion.

1. We would assume that the length of the string literal token was at least 2
2. We would allocate a buffer with size length-2

And when the stars aligned (one of which would be an invalid source location due to stale PCH)
The length would be 0 and we would try to allocate a 4GB buffer.

Add checks for this corner case and a bunch of asserts.
(We really really should have had an assert for 1.).

Note that there's no test case since I couldn't get one (it was major PITA to reproduce),
maybe later.
