[PATCH] Fix for gdb.tui/tui-layout-asm.exp

[Carl Love]

GDB maintainers:

The following patch fixes an issue seen on PPC64.  The issue is the
width of the columns of data in the terminal window changes based on
the amount of text in each column.  As the test scrolls thru the
window, the column widths change causing the check to see if the scroll
down one line works.  This patch makes the window a little wider so now
the column widths remain constant for the test.

This patch was tested on Power 9 and Intel without any regression
errors.

Please let me know if it is acceptable.

                            Carl Love

Fix for gdb.tui/tui-layout-asm.exp

The width of the window is too narrow to display the entire assembly line.
The width of the columns in the window changes as the test walks thru the
terminal window output.  The column change results in the first and second
reads of the same line to differ.  Increasing the width of the window keeps
the column width consistent thru the test.
