the one process we're interested in, instead of fetching all
of them and only keeping one.
(the old implementation made sense when we were doing the
initial find-this-process-by-pid-or-name by looking through
all the kinfo_procs.)

loaded. It locks onto *-apple-darwin binaries where the binary has
a "__KLD" segment. Soon I will modify the lldb_private::ObjectFile
class to return an executable type which will be an enum with values
something like:
eObjectFileTypeUserExectable,
eObjectFileTypeUserSharedLibrary,
eObjectFileTypeKernelExectable,
eObjectFileTypeKernelSharedLibrary,
eObjectFileTypeObjectFile,
eObjectFileTypeCoreFile
But for now we look at the section since a user and kernel mach-o
executable have the same mach-o file type.

new GetValueForExpressionPath() method in ValueObject to navigate expression paths in a more bitfield vs slices aware way
changes to the varformats.html document (WIP)

- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
to generate asm matcher subtarget feature queries. e.g.
"ModeThumb,FeatureThumb2" is translated to
"(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

argument expansion to use the macro argument source locations as well.
Add a few tests to exercise this. There is still a bit more work needed
here though.

pointers. Some of the spots are obviously initialized
later, but it's better just to NULL the pointers out
at initialization to make the code more robust when
exposed to later changes.

It was testing a linear scan feature:
Test if linearscan is unfavoring registers for allocation to allow
more reuse of reloads from stack slots.
The greedy register allocator doesn't access any stack slots in this
function, so the linear scan feature was not being tested.

instantiation and improve diagnostics which are stem from macro
arguments to trace the argument itself back through the layers of macro
expansion.
This requires some tricky handling of the source locations, as the
argument appears to be expanded in the opposite direction from the
surrounding macro. This patch provides helper routines that encapsulate
the logic and explain the reasoning behind how we step through macros
during diagnostic printing.
This fixes the rest of the test cases originially in PR9279, and later
split out into PR10214 and PR10215.
There is still some more work we can do here to improve the macro
backtrace, but those will follow as separate patches.

searching for variables and symbols in the target
more robust. These checks prevent variables from
being reported as existing if they cannot actually
be evaluated in the current context.

the normal case.
Before, for this:
$ cat t.c
int test(int x) { return x * 2; }
We would get this:
addl %edi, %edi
jno LBB0_2
## BB#1: ## %overflow
ud2
LBB0_2: ## %nooverflow
movl %edi, %eax
popq %rbp
ret
Now we get this:
addl %edi, %edi
jo LBB0_2
## BB#1: ## %nooverflow
movl %edi, %eax
popq %rbp
ret
LBB0_2: ## %overflow
ud2

numbers should be printed instead of symbolic register names in
MCAsmStreamer::EmitRegisterName. This is necessary because some versions of
GNU assembler won't accept code in which symbolic register names are used in
cfi directives. There is no change in behavior unless the flag is explicitly
set to true by a backend.
