Implement the .ltorg directive for ARM assembly This directive will write out the assembler-maintained constant pool for the current section. These constant pools are created to support the ldr-pseudo instruction (e.g. ldr r0, =val). The directive can be used by the programmer to place the constant pool in a location that can be reached by a pc-relative offset in the ldr instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197711 91177308-0d34-0410-b5e6-96231b3b80d8

@ This test has a partner (ltorg-darwin.s) that contains matching
@ tests for the .ltorg on darwin targets. We need separate files
@ because the syntax for switching sections and temporary labels differs
@ between darwin and linux. Any tests added here should have a matching
@ test added there.
