[Linker] Add directives to support mixing ARM/Thumb module-level inline asm.
Summary:
By prepending `.text .thumb .balign 2` to the module-level inline
assembly from a Thumb module, the assembler will generate the assembly
from that module as Thumb, even if the destination module uses an ARM
triple. Similar directives are used for module-level inline assembly in
ARM modules.
The alignment and instruction set are reset based on the target triple
before emitting the first function label.
