7b25ecf6ad ARM BL/BLX instruction fixups should use relocations.
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

0f0c411079 Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

34982576a4 Add support for the R_ARM_TARGET1 relocation, which should be given to relocations applied to all C++ constructors and destructors.
This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against.

51222d1551 NEON use vmov.i32 to splat some f32 values into vectors.
For bit patterns that aren't representable using the 8-bit floating point
representation for vmov.f32, but are representable via vmov.i32, treat
the .f32 syntax as an alias. Most importantly, this covers the case
'vmov.f32 Vd, #0.0'.

"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's

thing to do.
