We handle struct byval by inserting a pseudo op, which will be expanded to a
loop at ExpandISelPseudos.
A separate patch for clang will be submitted to enable struct byval.

so a process connect without any plugin specified picks up the 
gdb-remote plugin by default.

When the Platform launches a process for debugging, make sure it goes into a separate process group, otherwise ^C will both cause us to try to Stop it manually, AND send it a SIGINT, which can confuse us.

If the Driver's input reader gets an Interrupt and the current command line is empty, then treat that interrupt as an instruction to Stop the process of the currently selected target.

Anonymous union members within a struct are now properly handled as an unevaluated field in C++11 mode.  This fixes PR12866.

the confusion among all of the uses of Best* in relation to the set of
possible typo correction results. Also add a method to return the set of
typo corrections that have the single best edit distance--it returns the
second half of the first pair in TypoEditDistanceMap (with
getBestEditDistance already returning the first half).

For hardware watchpoint enable/disable, in case the kernel call to set the revised debug state fails, we need to recover the local cache to the previous known state.

 - compute size & offset at the same time. The side-effects of this are that we now support negative GEPs. It's now approaching a phase that it can be reused by other passes (e.g., lowering of the objectsize intrinsic)
 - use APInt throughout to handle wrap-arounds
 - add support for PHI instrumentation
 - add a cache (required for recursive PHIs anyway)
 - remove hoisting support for now, since it was wrong in a few cases

sorry for the churn here.. tests will follow soon.

now Reader and Writer subclasses for each file format.  Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.

We should lock the number of elements after the initial parsing is
complete. Recursive AST visitors in AnalyzesConsumer and CallGarph can
trigger lazy pch deserialization resulting in more calls to
HandleTopLevelDecl and appending to the LocalTUDecls list. We should
ignore those.

This patch will optimize the following
        movq    %rdi, %rax
        subq    %rsi, %rax
        cmovsq  %rsi, %rdi
        movq    %rdi, %rax
to
        cmpq    %rsi, %rdi
        cmovsq  %rsi, %rdi
        movq    %rdi, %rax

Perform this optimization if the actual result of SUB is not used.

Reg-units are named after their root registers, and most units have a
single root, so they simply print as 'AL', 'XMM0', etc. The rare dual
root reg-units print as FPSCR~FPSCR_NZCV, FP0~ST7, ...

The printing piggybacks on the existing register name tables, so no
extra const data space is required.
