Constants and Metadata share ValueList. This means they must be emitted interleaved (using appropriate BLOCK_IDs) otherwise ValuePtrs index gets out of sync.

Remove ARM specific getInlineAsmLength. We'll rely on the simpler (and faster) generic algorithm for now. If more accurate computation is needed, we'll rely on the disassembler.

Emit sub r, #c instead of transforming it to add r, #-c if c fits in 8-bit. This is a bit of pre-mature optimization. 8-bit variant makes it likely it will be narrowed to a 16-bit instruction.

TLI.computeMaskedBitsForTargetNode from ComputeMaskedBits, since
the former may call back into the latter. This fixes a major
compile time problem on a testcase that happnened to hit this
in a particularly bad way, PR4643.

implementation of '#pragma unused' by not constructing intermediate
DeclRefExprs, but instead do the name lookup directly.  The
implementation is greatly simplified.

Along the way, degrade '#pragma unused(undeclaredvariable)' to a
warning instead of being a hard error.  This implements:

<rdar://problem/6761874> [sema] allow #pragma unused to reference undefined variable (with warning)

few places in InstCombine to use it, to fix problems handling pointer
types. This fixes the recent llvm-gcc bootstrap error.

hey it uses .previous, so it should work :)
