On AArch64 the pseudo instruction ldr <reg>, =... supports both 32-bit and 64-bit constants. Add support for 64 bit constants for the pools to support the pseudo instruction fully. Changes the AArch64 ldr-pseudo tests to use 32-bit registers and adds tests with 64-bit registers. Patch by Janne Grunau!

@ This test has a partner (ltorg.s) that contains matching
|
|
@ tests for the .ltorg on linux 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.
