This parameter is useless because nowhere used explicitly and always
gets its default value - "false".

multiple stores with a single load. We create the wide loads and stores (and their chains)
before we remove the scalar loads and stores and fix the DAG chain. We attempted to merge
loads with a different chain. When that happened, the assumption that it is safe to RAUW
broke and a cycle was introduced.

Most of the pieces for this were already in place, but a proper EmitVAArg
is needed for aggregates and complex numbers to be handled. Although the
va_list for 64-bit PowerPC SVR4 consists of GPRs 3 through 10 together with
the overflow portion of the parameter save area, we can treat va_list as
pointing to contiguous memory for all parameters, since the back end forces
the parameter GPRs to memory for varargs functions.
There is no need at this time to model parameters and return values beyond
what the DefaultABIInfo provides.

1. Add mipsel-linux-android to the list of valid MIPS target triples.
2. Add <gcc install path>/mips-r2 to the list of toolchain specific path
prefixes if target is mipsel-linux-android.

instruction (for Intel Atom) was not being done by Clang, because
the type context used by Clang is not the default context.
It fixes the problem by getting the global context types for each div/rem
instruction in order to compare them against the types in the BypassTypeMap.
Tests for this will be done as a separate patch to Clang.

is not profitable in many cases because modern processors perform multiple stores
in parallel and merging stores prior to merging requires extra work. We handle two main cases:
1. Store of multiple consecutive constants:
q->a = 3;
q->4 = 5;
In this case we store a single legal wide integer.
2. Store of multiple consecutive loads:
int a = p->a;
int b = p->b;
q->a = a;
q->b = b;
In this case we load/store either ilegal vector registers or legal wide integer registers.

...and fix the run line so that the expected warnings are the same on
all platforms.

can't have the logic here to add in the 'tools/{driver,libclang}' directories,
because they will be added in for ALL Makefiles which #include the top-level
one. Place the logic into the 'tools' Makefile.

a memcpy to reflect that '0' has a different meaning when applied to
a load or store. Now we correctly use underaligned loads and stores for
the test case added.
