d65dfd8342 ARM: permit full range of valid ADR immediates.
This fixes an issue where trying to assemlbe valid ADR instructions would cause
LLVM to hit a failed assertion.

Patch by Keith Walker.

2fe71f8f7e LoopVectorize: Vectorize math builtin calls.
This properly asks TargetLibraryInfo if a call is available and if it is, it
can be translated into the corresponding LLVM builtin. We don't vectorize sqrt()
yet because I'm not sure about the semantics for negative numbers. The other
intrinsic should be exact equivalents to the libm functions.

52b4edf6a1 In GCC 4.7, function names are now forbidden from .gcda files. Support this by
passing a null pointer to the function name in to GCDAProfiling, and add another
switch onto GCOVProfiling.

f26b4f05b3 For each function that we optimize we initialize a new list of lib functions. For each function name we malloc memory. This patch changes the Libcall map to use BumpPtrAllocator. Now we malloc only once. This speeds up instcombine by a few % on a large c++ program.

8df7c39976 IR: Don't constant fold GEP bitcasts between different address spaces
PR15262 reported a bug where the following instruction:

  i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*),
                                i32 2

was getting folded into:

  addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0,
                                        i32 2)

This caused instcombine to crash because the original instruction and
the folded instruction have different types.  The issue was fixed by
disallowing bitcasts between different address spaces to be folded away.

06df83c25a Debug Info: for static member variables, add AT_MIPS_linkage_name to the

We have a regression for old GDB when Clang uses DW_TAG_member to declare
static members inside a class, instead of DW_TAG_variable. This patch will fix
this regression.

ac67b50fcf AsmParser: More generic support for integer type suffices.
For integer constants, allow 'L', 'UL' as well as 'ULL' and 'LL'. This provides
better support for shared headers between .s and .c files that define bunches
of constant values.
