Kevin Buettner c6f0b406f5 gdb.dwarf2: Don't hardcode certain constants in Dwarf::assemble constructs
Two tests in gdb.dwarf2, data-loc.exp and dynarr-ptr.exp assume that
sizeof(int) is 4.  This patch looks up the integer size and uses this
constant for DW_AT_byte_size, DW_AT_lower_bound, and DW_AT_upper_bound.

I discovered this problem while looking at test results for this
msp430 multilib:

msp430-sim/-msim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either

It fixes the following set of failures:

As I recall, there are still (other) problems with msp430 multilibs
which don't use -mlarge.

gdb/testsuite/ChangeLog:

	* gdb.dwarf2/data-loc.exp (Dwarf::assemble): Don't hardcode
	value associated with DW_AT_byte_size.
	* gdb.dwarf2/dynarr-ptr.exp (Dwarf::assemble): Don't hardcode
	constants for DW_AT_byte_size, DW_AT_lower_bound, and
	DW_AT_upper_bound.
