more efficiently when it contains a large number of items. Since
the map is actually a vector of "const char *" and type T values,
it will double in size every time you append to it. The extra
added functions allow the collection to be sized to fit the data
after all entries have been appended, and lookups by name or by
regex have been built in to the class to allow efficient lookup.

name is "lldb". So currently when you startup any application and you
have not specified that you would like to skip loading init files through
the API or from "lldb" options, then LLDB will try and load:

"~/.lldbinit-%s" where %s the basename of your program
"~/.lldbinit"

Then LLDB will load any program specified on the command line and then
source the "./.llbinit" file for any temporary debug session specific
commands.

I want this feature because I have thread and frame formats that do
ANSI color codes that I only want to load when running in a terminal
which is when I am running the "lldb" command line program.

using of instancetype. Test case uses other feature not yet
supported in the rewriter. There is more work to do, but this
is an ongoing task and not urgent at this time.

Use a more portable heuristic for deciding when to emit a single
atomic store;  it's possible that I've lost information here, but
I'm not sure how much of the logic before was intentionally arch-specific
and how much was just not quite consistent.

better.

Don't immediately give up when an add operation can't be trivially
sign/zero-extended within a loop. If it has NSW/NUW flags, generate a
new expression with sign extended (non-recurrent) operand. As before,
if SCEV says that all sign extends are loop invariant, then we can
widen the operation.

the lifetime of the block by copying it to the heap, or else we'll get
a dangling reference because the code working with the non-block-typed
object will not know it needs to copy.

There is some danger here, e.g. with assigning a block literal to an
unsafe variable, but, well, it's an unsafe variable.

I'm doing this now for completeness because I can't think of/remember
any reason that it was left out. I'm not sure it will help anything,
but if we don't do it we need to explain why in comments.
