for the debugger to execute for certain kind of tests (for example, a benchmark).
A list of runhooks can be used to steer the debugger into the desired state before more
actions can be performed.

The main motivation was to do typo correction in C++ "new" statements,
though picking it up in other places where type names are expected was
pretty much a freebie.

The VMOVS widening needs to look at the implicit COPY operands. Trying
to dig out the COPY instruction from an iterator in copyPhysReg() is the
wrong approach.
The expandPostRAPseudo() hook gets to look at COPY instructions before
they are converted to copyPhysReg() calls.

promoting allocas to preferred alignments that exceed the natural
alignment. This avoids some potentially expensive dynamic stack realignments.
The natural stack alignment is set in target data strings via the "S<size>"
option. Size is in bits and must be a multiple of 8. The natural stack alignment
defaults to "unspecified" (represented by a zero value), and the "unspecified"
value does not prevent any alignment promotions. Target maintainers that care
about avoiding promotions should explicitly add the "S<size>" option to their
target data strings.

callback. Individual instances of this problem are always bugs that
need to be fixed, but it's better to make sure we have initialized
data here.

movs r1, r1

we don't want this to be converted to:

movs r2, r2

and the breakpoint specification for the benchmark purpose. This is used by TestSteppingSpeed.py
to benchmark the lldb stepping speed. Without '-e' and 'x' specified, the test defaults to
run the built lldb against itself and stopped on Driver::MainLoop, then stepping for 50 times.

Allow targets to expand COPY and other standard pseudo-instructions
before they are expanded with copyPhysReg().
This allows the target to examine the COPY instruction for extra
operands indicating it can be widened to a preferable super-register
copy. See the ARM -widen-vmovs option.
