Chris Lattner af1bccec68 Fix a bug where RecursivelyDeleteTriviallyDeadInstructions could
delete the instruction pointed to by CGP's current instruction
iterator, leading to a crash on the testcase.  This fixes PR9578.

Chris Lattner cfe5aa65d2 Avoid excess precision issues that lead to generating host-compiler-specific code.
Switch lowering probably shouldn't be using FP for this.  This resolves PR9581.

Eli Friedman 17822fcde9 PR9604; try to deal with RAUW updates correctly in the AST. I'm not convinced
it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

Chris Lattner e53c95f180 fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

they thought they were, because alternation was expanding
wrong in {{}}'s.

Jakob Stoklund Olesen ed47ed4e80 Build the Hopfield network incrementally when splitting global live ranges.
It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

Jakob Stoklund Olesen 4ad6c160a5 Precompute interference for neighbor blocks as long as there is no interference.
This doesn't require seeking in the live interval union, so it is very cheap.

Caroline Tice 25d61ac2ed Fix various things in the instruction emulation code:
- Add ability to control whether or not the emulator advances the
    PC register (in the emulation state), if the instruction itself
    does not change the pc value..

    - Fix a few typos in asm description strings.

    - Fix bug in the carry flag calculation.

Ted Kremenek f603f3afbd Start overhauling static analyzer support for C++ constructors. The inlining support isn't complete, and needs
to be reworked to model CallEnter/CallExit (just like all other calls).  For now, treat constructors mostly
like other function calls, making the analysis of C++ code just a little more useful.

Devang Patel e39647951b Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array.
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.
