Take advantage that the 128-bit vpxor zeros the higher part and use it.

For PCH files, have only one open/close for temporary + rename to be safe from race conditions.
For all other output files open/close the output file directly.

This takes the new 'resume' instruction and turns it into a direct jump to the
caller's landing pad code. The caller's landingpad instruction is merged with
the landingpad instructions of the callee. This is a bit rough and makes some
assumptions in how the code works. But it passes a simple test.

use in KEXTs. However, users/Xcode still need to tweak the linker flags to do 
the right thing, and end up using -Xlinker, for example.  Instead, have the 
driver "do the right thing" when linking when -fapple-kext is present on the 
command line, and we should have Xcode use -fapple-kext instead of setting other
flags like -Xlinker -kext or -nodefaultlibs.

whether a register operand is in the right register class. e.g. mem operands.

llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.
