delete the instruction pointed to by CGP's current instruction
iterator, leading to a crash on the testcase.  This fixes PR9578.

Switch lowering probably shouldn't be using FP for this.  This resolves PR9581.

it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

This found a few problems in the testsuite, which serves as its test.

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.

This doesn't require seeking in the live interval union, so it is very cheap.

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.

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.
