ac7eae5b89 - When legal, promote a load to zextload rather than ext load. 
- Catch more further dag combine opportunities as result of operand promotion, e.g. (i32 anyext (i16 trunc (i32 x))) -> (i32 x)

eac9c07fde Identify when a lexical scope is split in to multiple instruction ranges. Emit such ranges using DW_AT_ranges. 
This patch fixes bug (PR6894) introduced by previous version of this patch.

fc0b860bcc Revert a small part of 102372; this fixes at least one 
of the dbg testsuite regressions.  I don't think this is
really the right fix; this change exposed an existing problem
upstream somewhere.

ee9eb411ff on darwin empty functions need to codegen into something of non-zero length, 
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505

per-basic-block state to group it with.

a063e19593 Run LiveVariables instead of computing liveness locally in -regalloc=fast. 
This actually makes everything slower, but the plan is to have isel add <kill>
flags the way it is already adding <dead> flags. Then LiveVariables can be
removed again.

When ignoring the time spent in LiveVariables, -regalloc=fast is now twice as
fast as -regalloc=local.

00207237dd Add fast register allocator, enabled with -regalloc=fast. 
So far this is just a clone of -regalloc=local that has been lobotomized to run
25% faster. It drops the least-recently-used calculations, and is just plain
stupid when it runs out of registers.

The plan is to make this go even faster for -O0 by taking advantage of the short
live intervals in unoptimized code. It should not be necessary to calculate
liveness when most virtual registers are killed 2-3 instructions after they are
born.

7609017dc3 Because of the EMMS problem, right now we have to support 
user-defined operations that use MMX register types, but
the compiler shouldn't generate them on its own.  This adds
a Synthesizable abstraction to represent this, and changes
the vector widening computation so it won't produce MMX types.
(The motivation is to remove noise from the ABI compatibility
part of the gcc test suite, which has some breakage right now.)

A testcase would be huge and fragile, sorry.
