Jakob Stoklund Olesen 237dceff90 Store sub-class lists as a bit vector. 
This uses less memory and it reduces the complexity of sub-class
operations:

- hasSubClassEq() and friends become O(1) instead of O(N).

- getCommonSubClass() becomes O(N) instead of O(N^2).

In the future, TableGen will infer register classes.  This makes it
cheap to add them.

Jakob Stoklund Olesen 8153f6c39f Extract a slightly more general BitVector printer. 
This one can also print 32-bit groups.

Johnny Chen 86268e4459 o lldbtest.py: 
Add a keyword argument 'endstr' to TestBase.expect() method to assert that the output
will end with 'endstr'.

Add TestBase.switch_to_thread_with_stop_reason(stop_reason) to select the thread with
the stop reason = 'stop_reason' as the current thread.

o TestWatchLocation.py:

Modified to switch to the stopped thread with stop reason = watchpoint and to evaluate
an expression with expected output for stronger assertion.

Greg Clayton 0bd4e1b8c9 Removed some commented out code from the DWARF parser. 
Also reduce the size of the lldb_private::Symbol objects by removing the
lldb_private::Function pointer that was in each symbol. Running Instruments
has shown that when debugging large applications with DWARF in .o files that
lldb_private::Symbol objects are one of the highest users of memory. No one
was using the Symbol::GetFunction() call anyway.

Jim Grosbach 24ff834671 float comparison to double 'zero' constant can just be a float 'zero.' 
InstCombine was incorrectly considering the conversion of the constant
zero to be unsafe.

We want to transform:
define float @bar(float %x) nounwind readnone optsize ssp {
  %conv = fpext float %x to double
  %cmp = fcmp olt double %conv, 0.000000e+00
  %conv1 = zext i1 %cmp to i32
  %conv2 = sitofp i32 %conv1 to float
  ret float %conv2
}

Into:
define float @bar(float %x) nounwind readnone optsize ssp {
  %cmp = fcmp olt float %x, 0.000000e+00   ; <---- This
  %conv1 = zext i1 %cmp to i32
  %conv2 = sitofp i32 %conv1 to float
  ret float %conv2
}

David Chisnall 3154e68bef Remove the conditional that avoided passing the Objective-C runtime specification flags to cc1. This fixes PR10369 (__builtin_NSStringMakeConstantString() selecting the wrong runtime in C / C++ code and crashing, although it doesn't fix the problem that instantiating the Mac runtime for non-Darwin targets was crashing.)

Duncan Sands 5c05579f94 Inlining often produces landingpad instructions with repeated 
catch or repeated filter clauses.  Teach instcombine a bunch
of tricks for simplifying landingpad clauses.  Currently the
code only recognizes the GNU C++ and Ada personality functions,
but that doesn't stop it doing a bunch of "generic" transforms
which are hopefully fine for any real-world personality function.
If these "generic" transforms turn out not to be generic, they
can always be conditioned on the personality function.  Probably
someone should add the ObjC++ personality function.  I didn't as
I don't know anything about it.
